I'll take the 383 but I do love the 360 as well. In an A-body the packaging is nice on the 360LA, but in a B/C body, I'll choose 383 every time. The downside is weight and the extra mandatory 727 parasitic drag when you can get the 904 benefits for free with the 360. Magnum heads and strokers make the LA start looking better, but bang for the buck, I'll still take the torquey big block!!

I currently have a 440 in my scamp and a 360 in my 79 little red express, and I have had one 383 in a 77 dodge ramcharger, I just prefer the 360 Cheaper to build and to add hp and the used parts market is much more available I find, and I ran the dog out of the 360's that I wont do to my 440, the 360 can take a lot of beatings in my opinion and parts are so much cheaper, as far weight differences my book lists the weight as 670# including manifolds, small block at 550#.. again just my opinion if you have an A body with a big block and a 727 gear it high nothing lower than a 323 and with the small block gear it lower 373 or lower even, again just my opinion for the street, thanks for the video Tim.

Never owned a big block ,just can't find one with a reasonable price tag or even someone willing to sell. Small blocks are were it's at for me.Thats all I know, I'm in a happy place around all A blocks . Easy and compatible fun for the win. Thanks for reading this have a wonderful day.

I'm a big block guy so naturally I'd choose the 383. However... I've built some pretty dang nice 360s in the past that I'd happily drive. Both are great engines so if I had to choose, it would boil down to what it is going in.

The 383 will get better MPG in a street application as well, I have never seen a 360 pull down any MPG. I got better mileage (by far) with my '71 Sport Fury 383/727/2.76 gears than my '92 D150 (transplanted) Magnum 360/5.9L-46RH o/d 3.55 (2.45 effective gear in o/d) or 2000 Durango 5.9L 2wd 46RE 3.55 gears (2.45 effective in o/d). I guess it's the shorter stroke? The 5.9 Magnums both have efficient multi-point EFI and the Fury had a Theromquad (that I added, along with the intake) off a '72 400HP.

I would have to be more mechanically experienced to have any type of intelligently formed opinion. But I do like the rumble of a big block! Lol

I'm an A body guy! Small block for me! I'd definitely try a 383 in a truck or a B body. I did have a 75 Dodge truck with a 383 many years ago. It was fun!

Plus it was easier to put points in the big block distributors being upfront.

I often say the engine you already have is the best place to start, but I like torque so 383 is my choice

The 360 is a good engine no doubt. But, the 383 even with its larger size and weighing more gets my preference. I've had many of both. The 383 consistently gets better fuel mileage for me. Pretty much bulletproof bottom end, the heads are much better matched for the 383 than the 440. I think Vizard said "the 440 was a big engine with small block heads". 383 rod ratio is really good. Nice to be able to remove the intake without any coolant loss. Distributor in front is a big plus. I guess it depends what each engine will be going into and the application.

360 all the way for me. Because I love small block Mopars! My all time favorite motors. Give a 360 some compression and they really wake up. That being said, the car that got me into Mopars was my parent's 383 Roadrunner..

I will go 383 every time, so much more potential

I have both I love both of them both rough good for a heavier car I like them if you have room in the big box nice anybody’s small boxes

I like your line of thought. I’d rather have a 360 in A-body. 383 is awesome. Look at their success in the roadrunner. But for me, the la is better suited for my 65 barracuda.

If I'm setting points, I'll take the 383. If I'm changing spark plugs, make it a 360! Oil pan gasket, 383. Intake manifold, 383.

If going for a small block, the 360, like you mentioned. Easier to work on. More room in an A body

With the invention of 360 stroker kits, The 360 is the Smart Move Because of the Size Difference. Even If you Don't Stroke the 360 the Power you can get for the Money you Will Spend gives the 360 the Win in my Humble Opinion. In the End It's All about Power to Weight. Thanks for the Great Video!

The 383 high performance cylinder heads are a good size for 383 power. In 1971 police car trials, the early 1971 high compression AMC 401 engine completely outperformed the 1971 low compression 383 engine. The 401 is more modern and had a compression ratio advantage at the beginning of the 1971 model year, though late 1971 401's have low compression ratio. The 383 engine is a "heavy" engine for a 383 size engine. The 1971 360 had flat top pistons but they were very far down from the cylinder heads, make them rather inefficient. The 1972 360 got dished pistons, that seem to work a bit better. The 360 has a much better, lighter weight, for a 360 size engine, than the 383 and the 360 is a more modern design.

The 383 is a legend. In a heavy vehicle, truck, B, C body. A 383.

It depends on what car it is going in. If its going in a challenger I would pick the 383. If its going in a Duster I will pick a 360. Great video as always.

Mever had experience with big blocks. Everybody wants 1500 for a non running that was pulled 15 years ago. I can tell you that the 360 is awesome. Dont like the bore size? Bore it 40 over to a 340 size. The 360s extra stroke makes it an awesome engine. For a small block.

Because I have A body cars I am happy with a 360. I know people with big block A body cars. Greatvan a straight line but they don't handle bends very well. Suspension is not designed for the weight either.

383 Magnums are NO jokes stock ! Rode in a 71 challenger with one, its a Beast ! 😁👍

Man oh man, you opened a barrel of pickles with this one! 383 all the way! I’ve got to go on the weight comparison video I had a while back. Let’s buy some aluminum heads and have a low deck party! In my last 3 years of pulling transmissions and swapping converters, I prefer the big block swap now. I can reach the bellhousing bolts, and not worry about those pesky 5-7 plug wires rubbing on that header. What’s a 904? 😂

I had 2. 1966 convertible Belvedere two and a hardtop at the same time with 383s very fast and super dependable I couldn’t tear them up.

For a stockish or mild street build in an A-body I would definitely go for the 360, lighter and easier to work on. For a max all out build the 383 would probably be a better choice just because you can bore and stroke it to almost 90 cubes more and you will make more power.

Depends on car size. 360 small blocks are great in smaller cars like A bodies.. I prefer big blocks in B and C bodies and trucks.

I like both engines, they both have their pros and cons. The 383 is a shorter stroke engine, which should make it quicker revving than a 360. But the 383 is also heavier, and heavier in the worst place - the front of the car. I tend to lean toward the 360 because of the weight savings, and also they provide a lot more space under the hood and headers are easier to live with. If I were to have a 383, it would have to be in a B or E body (or C body or truck) because there is more room under the hood. A big block in an A body is just such a tight fit, and the weight distribution is not good.

Since I 2 duster 70 charger there all 360 power for me it room under hood 318 mag in a dakota only small block Since my first build 1989

440 or go home!!! I have a 1970 Cuda with a stroked 440. This VS 502 is one heck of a power house and it was my ticket for a Division 1 title. 360 are boat anchors, put the money into a 440 and stop thinking about the weight difference. The power increase of a 440 will make up for the weight difference.

YOUR KIDDING ...RIGHT! no stock 360 318 or 340 can hold a candle to the 383 big block!.. then add money no object and still the 383 is the better choice!...... just one thing no coolant in intake manifiold gives the 383 the advantage big blocks are king!

A couple of years ago, a friend of mine wanted to revive his long dormant 1968 New Yorker. 440 was seized. I had a well worn 383 from a Polara. Got him on the road for a year. It became his daily driver. Then he got the itch to swap in an LA 360 from a 79 Newport mainly for the availability of consumable parts. He says the power change is almost unnoticeable. But a gear swap is next for the grocery getter as his town driving rarely get the long legged car into 3rd gear. He finds comfort in being able to walk into the parts store and walking out with parts same day, as opposed to waiting on ordered big block parts.

Well…… this comment is going to anger a lot of people, but it’s true. My Dodge just happens to be a big block car in vin. So about two years ago, I decided to go shopping for a big block for my Dodge, since mine came with a 383. I found one on craigslist that was marked down from $8500 down to $3200, I drove to the mountains here in Colorado and got it picked up. it came with all of the fancy names like Keith Black Pistons! Lunati voodoo cam! Solid roller crane cam rockers! My expectations were that I finally found an engine that’s gonna put me in the 12s so I pulled out my tired 400 big block and installed this supposedly hot little 383 in my Dodge. To my dismay, I cannot get it to even get into the 13s here in Colorado. Now you’re probably thinking that I’m doing something wrong and you’re probably right, but I have FBO ignition, 456 gears, brand new 750 carburetor. I cannot help to think I made some mistake. The guy that built the engine told me that I just got better heads then I would be able to dip into the 12s here in Colorado. This is obviously my next, but quite a big investment since I already have closed chamber heads on my Dodge with 10 1/2 to one compression. But I am going to try it anyway. Don’t get me wrong, I still love my car and have fun with it and it drives like a new car and runs great. I just want to go faster! Did I make a mistake. Should I have small block? Or 440?

I'v had both and prefer the small block it is easier for me to get around and work with take an intake and heads off in the car much easier I don't care for the distributor location on small block butt what are you going to do preferred LA to Magnum but that has mostly do with engine controls

I prefer a 383 and more likely the 400 really . But if you want one and have the other in car it is very costly now to do engine swap compared to few years back. best if you had a small block being able to utilize the existing drivetrain and just beef those up. same for keeping a big block. it the weight seems like much well not really , you can just by bolt on replacement big block heads.

Great video and thanks for posting this question for all of us to chime in on, I’m not really biased or highly prefer one more than the other I like ‘em all from the slant 6 up to the 440 including the Gen 3 hemis, i do agree with you that a small block in an A body is the way to go for the very reasons you mentioned 👍🏻👍🏻

I’ll take the 360, in part I think because everyone dumps on it so why not. And if does give you more room in the engine bay, and sometimes the lack of a head ache is enough.

360 in an A-body. 383 in anything else.

I bought mine first mopar 5 years ago, it is a 69 coronet 2 door hardtop wilth a 360 and 904.. the car whas not running when i bought. Before i even looked at the engine i was like " B body needs big block" But i was curious at the 360, it was mildly build with headers, Edelbrock intake, 340 J heads roller rockers etc .. and 904. Has a shifter kit . I started the car up, and drove it around.... Man i was impressed.. it was high reving and fast. Even smoked some standard big block cars So i im going to keep the 360, want to rebuild it with aluminum head and thinking of a stroker kit. It is lighter and hase useble HP an torq. What is 600+ hp if you don't can get it on the ground

I rescued my 383 like a stray dog. Its in my challenger for resale value. It used to have a 340. The 340 was a stronger higher reving engine but it did have a 6 pac and 391 gears. Never thought of the 383 as a taxi motor. Thats the 318 s job. The low deck big block fits nice and with aluminum top end it weighs the same as a small block.

The newest 383 is now 54 years old. The newest Magnum 360s are still running on the roads and filling the junkyards for cheap. B engine 727vtransmissions have been harder to find for decades. All forms of Torqueflites and 4 speed automatic versions fit the 360(mileage and driveability advantage right there). The Chevy and Ford Cascar series rivals call the 360s "baby Hemis", because of their unfair torque advantage coming out of the turns. K frame changes and motor mount issues for smaller Mopars add expense and complication to using the 383. The rest of the reasons have been well hashed out by others. I grew up with high compression 383s and loved em'. I was also one of those who looked at the new 360s as weaker, yet plenty thirsty options, until Ed Hambuger and his 340/360 shop changed all our minds on the 360.

Traded in my 67 GTX conv w/440 super commando on my 72 Demon. The insurance companies came after the muscle cars back then. $100 a year went to $100/mo. I miss the GTX. Been since 72 since I owned a BB. But I’ve liked the small blocks. Have a 360 in my Demon. Makes a good driver. Light enough to rip pretty good.

ive seen small blocks at the strip on on the streets racing and out do a big block especially due to weight. but i also like big blocks , slant6s ect. Also a big block in an A-body is a great choice as well weight ratio

Some say 383 has better crank less bottom end issues. Generally speaking, there's no replacement for displacement. The number you quoted did not include at what rpms. On a graph of HP and TQ, I beleive the area under the curve is more important than peak numbers.

No big blocks exist where I live anymore, of any kind.

Ima 360 for a few reasons ...way more parts and support w aftermarket. And weight between the two and a more modern engine line. P.s i have a truck so 360 for me good video

My uncle had a 78 power wagon with a 360 and it was a slug and got terrible gas mileage. I’ve seen some great running 360s at the track. You can make any engine perform and the a body argument is a good one. I love 383s raced them for years. I prefer them to 440s. 383 revs quicker and higher and lives longer doing it. What little you lose on the bottom end it more than makes up for in the mid range and higher rpm though the traps.

You make some great videos, Tim. You ask great questions too! I love a B or RB, but the LA is sure lighter...

A big block Mopar with Aluminum intake, heads, isn’t much heavier than an LA.

After messing with 360 timing in my pickup truck - I would much prefer a big block. 😁

The only stock 383 to 360 comparison I have would be my '71 Charger 4-bbl to my old 1976 Cordoba 360 4-bbl,, so last year 383 to smogged out 360 the 383 wins. Closest mild modified versions would be when I rebuilt the 383 with the high compression flat top pistons (still only in the 9ish to 1 ratio) with the crower 271 compu-cam, stock rockers, 906 heads with stock size valve, and mild port cleanup sand weiand intake. vs 360 with 9ish to 1 flat top pistons, stock heads/valves with mild port cleanup, small crower baja beast cam (I think 210? @ 0.050" duration) I think it had a holley street dominator intake and 600 holey carb. That 360 was built for torque and ran really good with decent gas mileage. I think that might be close to or better than the stock 383, but not the modified one. 360 I have now is KB-232 quench dome pistons, stock iron heads but with the larger valves and hardened exhaust seats. Good amount of porting, and milling (for quench), but righ around 9.5:1 compression. The Hughes Engines 216/220 duration cam with 1.6:1 aluminum rocker arms, Edelbrock Performer with EGR intake, port matched, and 670 truck avenger carb (about to convert to sniper efi.) This 360 would might have as much peak horse power (or more) as the modified 383, but with a larger torque curve. It's a nice combo. Wish I had money to engine dyno it as it seems stronger than I thought it would have been? One thing I noticed is I never had overheating issues with the small blocks, where it is more of a problem with the big block cars I have, but again, not a good comparison because the 360s were in trucks and the big blocks were in B-body cars? FWIW, the 360 was in the RamCharger I rolled, and is now going into the '69 Coronet 500 replacing the 318.

I have to say I do like both engines, but if I had to choose, I would be hard pressed not to go with the 383 mainly because of how easy it is to work on. It's hard to beat the dizzy up front, the dry intake, the external oil pump, and the 4 bolt water pump, but you're exactly right. What the engine is going in plays a big factor for me it just has to make sense.

What a great comparison. With that said, this one is really application driven. The 360 is a decent small block ( although the 340 is better IMO) but the potential for more power in a racing application is where the 383 shines. I would prefer the larger bore size of the 380, especially with modern Fuel Injection and boost.

Had a 66 383 originally a 2 barrel version, tore it down went with .30 over with heavy TRW 383 magnum replacement pistons, worked out to be 9.5:1 compression with a pair of 906 heads cut 0.28 due to pistons so far in the hole. Mild porting job on heads and a torker2 intake stock valves. 484 mopar performance purple shaft cam. Crane roller tip rockers and a mopar performance electronic ignition kit and distributor, 750cfm holley mechanical secondary carb. Hooker 17/8” headers, 3,000 tci converter and 727 automatic with turbo action manual valve body, dana 60 rear with 4:56 gears and Hoosier p295 quick times tires in a 83 ram D150 short bed full weight 3,700 pounds without driver best time was a 12:50 at 109 mph with a 1:83 sixty foot way back in 1992 so I guess you know which i’d pick nothing against the 360 great engine 👍

As a guy that learning about building motors. I’ve learned that big blocks cost big bucks.

I've had a number of both and would 'probably' take a 383 but I will say they are not as tractable as a 360 due to the short stroke, rotating mass and for an over-square engine has a pretty short stroke for a big block. A 383 NEEDS to be treated like a BIG small block engine. No huge overlap or gigantic cams. Just be conservative and it'll perform. With current or even past pistons it's tough to get the compression distance where it needs to be or you'd want it. There aren't nearly even a fraction of the parts to make a 383 build perform anywhere like a 360. It's really just a matter of the image of a 383 or the ease, practicality and performance of a 360. The LA version of the 360 was never 'really' a performance engine. It had a 340 cam, double roller timing set and TQ and dual exhaust (factory). I really ever only had ONE 383 that was a 'screamer'. It was a worn out (100k+) '71 Road Runner with an auto and 3.23 gears. It was bone stock and would run rings around some 440's I owned. Must have been one of the cars that came together with just the 'right' tolerances. It was low compression and had the factory Holley too. It was impressive but I had a stock E58 that I 'super tuned' to at least that level. So my answer is a 360 is easier to make perform all around and would be easier to make out perform a 383. Funny story. I have a '70 Dodge W200 PowerWagon with a stock 383 HP (original). It has 383 Magnum fender badges (factory). I was at a truck stop/diner a couple years ago and drove my truck and some guy (saw the badges) and says 'That has a stroked Chevy engine?' I just turned around and walked away.

I'll take torque of the big block 😬😬

360 is my favorite. More room for working on things. And lighter.

"la" had that valve lifter bore angle inherited from the polysphere issue causing issues above 5500, so if you are going to run it hard with the stock block the lifter angle in the 383 is the better choice. ps I had an uncle with a 383 2 brl would get 25 imperial mpg.

I love my 65 Dart 273.Personal preference

C body guy here. Love the h code 383 in my 68 sport fury convertible. 4 speed taboot. I’ve been well served by 440 source heads and small lunati voodoo cam. Big block just looks better in a c body. Both are fine tough mod worthy engines. 383 has better design though

I prefer the 383 I’m currently building a 383 stroked to a 431. And I am putting it in AA body it’s gonna be tight but I’m using 19 7071, HP High Flow exhaust manifold . Thank you for the info I enjoyed the video.

I’ve thought about putting a 383 in my 75 RR because to me the 383 is the engine that made the Road Runner. If I had weight or packaging issues, like with an A body., I’d go 360.

I have had both a 383 and a 360 la in my 72 Cuda. 383 had much better power but the 360 greatly improved car handling. Pick your poison.

I've got an e body with a magnum 360/904. Mild cam. I love the handling and extra room around the lighter small block. I also have a 78 D200 with a 400. It's a great motor for that truck! Probably a little more torque than a stock 360 would have.

I tried the 383 and it wasn't what I wanted so I went with good old 440. Attempting to do a 4 barrel swap on my first 360 so I guess will see how that goes. I really like the old reliable 318.

360 small block any day and any year.

Modern day 6.4 scat pack is my preference. Even has back up camera 8speed auto that I could shift on the stick or paddles.

Ill take the 360. Both are great choices though. I just like how many there are still out there. Especially with the magnums in the junk yards

I’d eventually like to build a big block for my coronet. But for now swapping in an early 360 just because it was cheap and easy. Bought a running 360 and transmission 727 out of a motorhome for $500..and it’ll bolt right in place of the 318/904 that I blew up years ago.

Hi love the channel and the videos. I have a 1969 Plymouth b body. The oil pan is touching the motor mount on the passenger side only. It has a grove in the pan lip. Is this a symptom of bad motor mounts? Thanks.

I prefer the 360. We are mainly smallblock based so i have tons of parts already though.

I have a 1929 Dodge Brothers coupe. it has a late model 360 Magnum setting in it. On top of the motor is a 4 hole carburetor.. In front of it is and electric fan. Behind it is a 904 with a Mustang rear end. You better be wearing Pampers when you get on it !

I had a 73 roadrunner 360 4barrel. People that rode in it always said it felt like a big block because the power and torque they could feel. E58 engine

Had a 360 great engine still lives in my dads car went to a 413 incredible engine 6yrs just destroyed a lifter now going to a 69 magnum 383 can't wait!

I had the choice between the LA 360 and a 440 motorhome engine for my 74 D100. I chose the 360.. you guessed it, weight difference. The other reason, I had a 318 already, makes the swap easy.

I've got a 360HD 4bbl in my 1980 Dodge B300 MaxiVan. Great engine, super easy to work and strong as an ox!!! 🐂

If I'm building a cruiser, ill take the 360, and put a 518 behind it. The Magnum 360/518 can still be had for less than $1000 complete. Add a 3.91 rear gear, and cruise at 2300 rpm or so at 70 mph. If I'm looking at a street brawler, I'd go 383, and build it as light as possible. After seeing @JustMoparJoe video on weight, it took the weight advantage argument for the small block and threw it out the window.

I am of the mind it depends on the application, what is it going in and what is its intended use!

I like them both! The issue with 360 swaps is the external balance cast crank, and you can't swap 318/340 oil pans onto a 360. On the other hand the small block will bolt up to the 904, 727, 518/46RH. I also like the small block spark plug access and overall smaller size. The 383 is internal balance, and oil pans swap with other big blocks. Hard to compare stock performance as it would vary by year and if 2 or 4 bbl carb (or Magnum EFI), and then if the 360 is LA vs. Magnum? They can both be modified to meet the users needs. The Small block lifter angle has never been a problem for me, but my 360's stay under 6,000 RPM. Note that if you are going to put a 6-71 blower on a stroked 360, use the forged crank! The 383 larger bore can use heads with larger valves, and an easy 496" engine stroked. Make the heads, intake and water pump aluminum and not much of a weight penalty.

B-Body guy here. Give me the big block.

I have a 360 magnum in a 1963 Plymouth val.love it.but my favorite is the 383.just the 360 I have a little more room.thanks for asking

I’d be happy with either one right now ..both my mopars are rollers at the moment

I actually run both, my Warlock is a 360 but I took a 318, 3 on the tree out of my 76 & put a 383 4sp pistol grip....love them both

Depends on what it is going in. A body 360, c and b body 383, e body either

360 in a a body, 383 in a e body

Small blocks for me.

383, without a doubt. It's commonly referred to as "the big block that revs like a small block", so it's the best of both worlds. The 360 only revs like a small block. Sure it's a decent and powerful small block, but it's no big block and won't have equivalent torque, with all else being equal. The 360 only wins when it comes to price point and availability. Also, when people ask you what motor you have in your car, nobody's going to be impressed that you have a 360. Ease of working on them doesn't matter to me.

I’d like to see another 318 v 360 magnum poll. I’ve seen many high torque builds lately with these engines. Most I’ve seen say that a striker 318 is more durable with the same outcome due to more cylinder wall. I think for a cheap street/strip car you can build an amazingly fast stroked 318 magnum.

383 .030 block + 4.25 stroke = 550 hp with stock Pro Comp heads. My buddy has one in a '70.Dart with a mild .520 hydraulic roller & it's a beast! Same car with a fairly aggressive 360 was also a beast. Toss up between them. I'm more of a small block guy though. I've accumulated enough stuff where I can make pretty good power with a 360 based stroker.

I would go with 383 unless space was an issue. My first mopar was a 74 Roadrunner with a 383 in high-school so part of it may be nostalgia.

When I was a kid I had a '69 Dart with a bone stock 383 4 bbl. 4 spd......it was brutal. Then I had a '73 Charger with a 318 2 bbl. and got $h!t on by every mainstream 350 with a Quadrajet......sure would've loved the Dart set-up in the Charger!

if you are talking about engines for A-bodies only, the lighter, smaller 360 is a great choice. A-bodies were not originally designed for any V-8 motors. The 383, which is a "B" engine, was a very tough fit. My next door neighbor bought a 1967 383 formula S Barracuda brand new. He had to buy a special tool to get to the spark plug nearest to the firewall on the driver's side. There was no power steering, no A/C or power brakes, because there was no room for them. The engine was in the car tighter than a tick on a dog's hind leg. The LA engines were much better fits in the later A-body cars. As for the 383, you should stop calling them "taxi cab" engines. They were nothing of the kind. They were very durable, strong running engines that were often used in police cars. I was there for the entire muscle car era, and I have never seen a taxi cab with any Chrysler big-block engine, much less a 383.

360 versus 383.. .. Both are great engine options For me its the 360 over the 383 for pretty much the same reasons you listed... The small block is just easier to work with especially in a car more room ( however this perspective is coming from a guy that works on his cars and prefers to have most room possible and less weight) even in a b-body or c body car I'd probably still stick with the 360. But only because it would be super easy to work on... That being said a 383 in a big block and a b or c body car would have the room for the engine for a mechanic to work on but it still won't have as nearly as much as the 360 would.... ( To me that would matter) The other thing I would note is that both the 360 and 383 have great aftermarket parts I would give the s edge to the 360 over the 383 in that department... ( A little bit more availability with the 360 and a little less cost for the 360) Especially with stroker kits it is just a fact that stroker kits for the 383 are going to cost more than they are for the 360... It will definitely cost you more to get cubes out of the 383 versus the 360 stroker kits... Obviously 383 will probably have greater head flow potential in the racing arena and greater cubic inch potential... And for a guy with a big car I can understand why they would pick the 383 over the 360.... But once again this is just my opinion and it's basically based on the fact that I work in my cars and love to have the most room as possible to fit aftermarket parts headers transmission lines etc... the parts are lighter and easier to handle... But once again if you're a guy that either (A)doesn't work on his car much or (b) is going for all out horsepower potential the 383 would be your choice...

I've always liked my big block's more than the small block mopars I've had but probably like the small block in the A bodies the best, but then again the 383 fits the A body real well, the 440 tall deck kinda gets too close to the heater motor in A bodies for my taste. Hard choice, i love them all!👍

I've got a 360 in my Duster, it fits well and has the potential to make gobs of power if I were to hop it up. I love small blocks becuase they are affordable, lighter, and can make big block power. However I can't really see a small block in a B or C body, those cars were made for a big block. My 68 Charger is getting a 383 and 4 speed, because that's what I think is best for that car. My truck will also get a 360, but that's mainly because I have the engine already and the truck was setup for a small block. So it really depends on the car and what you're doing with it.

With stock stroke home build, it's pretty even. The heads, homeported, are pretty equal. The 360 has about a 60 lb weight advantage with similar equipment. Both with a pump gas CR will be at the 400 hp level. With stock displacement, I think I would pick the 360. If stroked, you will not get easily over 408 with the 360. With more expensive cranks you can go to 426. A 383 can easily take 4.25" stroke for 496 cu in. That is a difference. Easy to get to 500 hp level with basic parts, and at low rpm. Not so with a 408, you will be around 50 hp behind and at higher rpm, less tq.

Put that 383 in your duster then get back to us

The la and the b/r have different transmission bolt patterns. You could get a A518 od transmission if you weren't racing it. The la is eazy to get to the spark plugs. The 360 and the 340,318 and the 273 are balanced different. If you wanted fuel injection you could pull the whole harness and computer from a truck or van.

What came in the car from the factory? That's my favorite engine for that vehicle.
