For the wiring harness for ls....buy a pulled ls with computer and harness for the same price he listed for a harness. You gotta extra motor to play with. I have both old school and new school. I'm a decent tuner and that knowledge will cut cost for ls swaps. Good heads for old school sbc will determine how good it is. So, someone who doesn't understand the operations of an ls will be intimidated naturally. A good set of heads for sbc cost as much as a pulled ls with sensors, intake, fuel rail and injection, computer and harness and accessories at this time. I see both sides having both sbc and ls. But some of those costs you can cut if you are willing to learn the fuel injection and operating system.

I ls swapped a jeep for around 4500 doing all the work myself, it runs amazing and the milage is on par with to 4.0

350 and lm7 engines are the best, you'll never go wrong with either one

For the past 32 years I've only owned Chevy trucks. My first vehicle was a 76 Jimmy with a 350 small block and a turbo 350. My current ride is a 09 Tahoe SSV with a 5.3 and 6L80. However I did pick up a 77 Sierra K15 for a project truck back in November. Both the gen 1 small block and LS engines are incredible marvels of engineering. They both have their place and I understand why people do the swap. I'm old school and like the simplicity and ease of working on an old square body. No nonsense, no bull$#!+ extra features or options to cause problems. I believe old truck old engine. New truck new engine.

I chose the sbc for my s10 for several reasons. 1st being the v8 swap kit was cheaper 2nd was I already had a vortec 5.7 4 bolt. Did the head porting and lapped the valves myself. Screw in rocker studs and beehive springs. I built about 425 hp for less than 3500. Also I think the gen 1 is a better looking engine.

Spun a bearing on my 406 sbc in my 68 Camaro.Friends tried to talk me into an LS swap.Yaaaa right are you kidding me.Everything already lines up.Even though I ended up putting a lot of machine work into this now 408,bore,line hone,square it,deck it and a new balanced bottom end.When all said and done with gaskets,oil,ex ex ex it came out to $4000.I am glad I did not listen to my friends.I already had manifold,carb,headers,brackets,radiator cooling system,charging system,wire harness ex ex.When we lined up the cars and he had his 5.3 LS to my 408 sbc.This 408 torque kicked in and just pulled on him so hard it wasn’t even funny to him.Long live first gen.First gen FTW!…..Love the mechanical side of things.So much easier to work on.

I’m doing a complete LS swap wiring harness and transmission. I’m leaving it stock as that is about 150hp more than the original sbc. It should come in under $2500

Great video brotha, I myself am an old school kinda guy but I think the ls engines are great for the power and efficiency they provide but building one is still more expensive than building any small block or big block Chevy when you consider everything other than the block. Out here in CA the average cost of a ls swap into a older vehicle is always above $7,000 and that's if you do the work yourself. I myself just bought a early 90's RV for $700 with a big block 454 with only 28,000 miles on it that I'll be transplanting into my 84 C10 😁 I figure when I'm done I will probably be into it for a total of around $5,000. You just can't beat the look, sound and power of a big block Chevy just my opinion

This just made mind up to stay old school, great video!

Ole school uncle buck keeping er real .... Like em both their different animals period i love both 🤣

Love the video, built a 350 SBC with a 650 cfm carb and a mild cam from summit from an old vortec block my 93 sings the song of muscle 💪🏽💪🏽🔥🔥

LS can run a carb just like the sbc.....intake 250.00........msd coil control 500.00... Bang for buck , the carbed ls will make more power in an easier to drive package . The valve angles are more efficient , so you can run a milder cam and make more power . Here is my experience and it really opened my eyes on ls potential . I have 2 cars , a 68.camaro and a 72 camaro. The 68 was built to run hard and go low 11s . The 72 was built to be an all around cruiser , but with good power. The 68 had a built 406, 220cc aftermarket heads, 11.4 comp, big solid cam , etc . At 2900lbs , it ran 11.30 at 120 . The 72 had an ls3 w a simple conversion to carb like I described above , a set of headers, and a very streetable , small cam . At 3400lbs the 72 ran 11.60 and 120mph . The 68.was setup for hooking at the track w 4.10 gears and had no accessories on the engine. The 72 had ac and ps w 3.42 gears and was designed to be a multipurpose car. With limited traction , the 72 ran within 3/10ths of the 68 that hooked solid. The ls setup was a mild street build and the 68 was set up for the 1/4mile. The 72 was 400 lbs heavier and anyone could get in it and drive it like a new car . The ls costs about the same if you build a gen 1 to make power and carb a performance ls engine w a street cam. The ls makes power very easily and in a much milder package, will run with the sbc that is difficult to street drive by your average person . I like both, but the potential of the carbed ls is hard to.ignore . Just because the ls comes w an ecu and plastic intake doesn't mean it needs that to outperform a similar carbed sbc.

They are both great engines. If I had a car with no engine and had to purchase engine mounts, accessories, exhaust, etc., It could definitely make sense to put an LS in it. However, I love spanking the LS powered cars with my 8 second old school smallblock powered '69 Camaro.

I still like the simple old school SBC but the LS stuff is nice

I have a ls1 in my 68 and am currently looking to swap it back to sb327. Ls should never be in an old car!!

I love the torque the sbc puts out!!!! ❤❤

Just bought an 88 k5 350 TBI that I daily and have had an 80 trans am with 350 SBC from a 69 Camaro . Everyone says to LS swap. Why? They both Start right up and go. Do I want more power from the TBI sure but it’ll be cheaper to rebuild what I have that’s known to last. Oh and less wiring

I feel like you pumped the numbers up a bit on the LS side. Such as buying sensors and accessories. And a 1200-1400 holley terminator. For barlely more than your $1200 core estimate i could buy a 6.0 complete with computer, harness, sensors, and all accessories for $1500. From there buy a $350-500 standalone harness for the factory computer and youre golden

OG Small block 350 all the way. (For me,my opinion only) love the Video comparison.

Bought a 78 c10 that’s been sitting for 15 years changed the battery starts right up I’ll stick with the 350 small block one day the c10 will haul my ZL1

The swap mounts can be bought for around $40 now.

I'd go with a World Products Motown SBC/LS block (small block on the bottom, LS on the top) - best of both worlds...

My friend has an s10 with a 350 . He's did a some work to the truck such as new brakes , wheels and tires, but the engine is stock as far as he knows. I'm here to see if I want to rebuild that 350, or LS swap it. He was told that 350 was from a vette, but we haven't checked the numbers yet.

I went with an old school 400 in my ‘85 GMC

It's not easy or cheap to do it right. I am doing a LS3 in a 77 Trans Am and it is taking me a lot longer than I thought.

Ls swap into square body ...low milage tahoe smashed by a tree....750 bucks.... motor mount plates 25 bucks ...high presure fuel pump and lines 100 bucks...flywheel 135 bucks....vats tuned computer 100 bucks....do the wiring yourself it's easy....And twice the mileage of the 454 I took out......

I am debating this now. Have core 350, and 5.3 sitting here. 5.3 would be carbed in my application... but the msd box is +/- $500. Headers, 400 for less expensive deals. Those are biggest hits, in my opinion. Cams are same $ either way. But 5.3 lifters are less $. AFR heads a +/- 1000 everywhere. A sbc victor jr is over 400 now. In the long run its almost a wash. Core sbcs are getting harder to find as well....

Love my gen 2 SBC LT1. It does cost to work on it and build it but still cheaper.

In a square body Chevy you use a 1987 tank for efi a 3 pin heat temperature sensor oil sensor adapter

I think you just changed the direction of my whole build.

I think it depends on your application. Plus, what you already have access to. If I’m building a car/truck for the strip, I’ll probably head for an LS. If I’m staying on the street or cruising, and I already have the SBC in the vehicle, I’m staying put. My project is an ‘03, and came with the LM7, so naturally I’m sticking with Gen III LS. So, for me, it’s about dancing with the girl you brought with you, lol.

I have a 383 sbc with a th350. Everything is nice. But as ive gotten older. Id probably go LS and overdrive for more comfort. And definitely much less power😂😂😂😂

Another thing, coolant fans won’t cost you that much, why would you need to replace the radiator? Also what vehicle would you putting it in? Factory EFI? Aftermarket EFI? Or Carb? (LS). Also keep in mind the only LS that you can find in the JY that will have 400hp stock at the flywheel is a 6.0. Now you talking money, more than you put down.

Give me old school ANY day of the week!! I have no interest in that LS business.

I got a sbc 355 with duel quad carbs. For my street c10 that’s all the power I could ask for

Not to mention the brain and stuff for the ls

Big Block+Box= Perfection.

Might as well buy a car or truck with all the parts you need just a transplant no problem for seasoned mechanics much cheaper in long road...

Ls 5.3 iron block with carburetor.

Engine mounts for the LS swap generally $65 that are adjustable.

I wonder if it would just be easier doing a big block vs LS. And which one would work better

I rather have the sbc . If I was going to swap a motor. I am going and find a doner car/ truck with a big block and a trans. Hell I have a 95 4x4 that I thinking of doing a 350 and th350 swap on.

What about the gas prices and the mileage at a 1.50 per litre and the difference between a us gallon and a canadain gallon 3.78 litres 4.54 litre s for a gallon in Canada? And can’t forget the driveability of efi lot less dicking around the a carb

Progressive boost and stuff is fun to mess with. I'd honestly take a big block chevy over both

Take that two grand and buy a holley sniper EFI or whatever plus 180 degree headers, which to choose?

HARRUMPH HARRUMPH!!!

Junkyard. Junkyard. Junkyard

400 hp isn't much < 500 hp...you can get an entire vehicle to swap a LS and make more power (will cost more, but 100 more hp easy to achieve >500 hp...SBC is the way to go hands down no argument

Your a little off on your prices depending on what you put it in. For a lemans oil pan is 300 motor mounts are 150 gages will work with the factory gages you can use the stock computer can use stock rad intake is 400 I went carb.you can still use the stock computer for timing only. Only 2 extra sensors crank and cam.you can get a 5.3 for 250 from a yard headers for decent ones are around 300. I ran both stick efi and carb. If you run the stock efi then your not buying a carb or intake. It cost me about 1700 for motor and install stuff. Can use all the stock brakets from a lm7. I'm no hyped ls guy the only reason I did the swap was cause my 455 needs rebuilt and pontiac stuff cost way more then chevy stuff. I had a 72 455 in it and I put a toqurestorm supercharger on it its a smog engine and the straight out of the junkyard engine with no supercharger on had more power then the 455 yeah makes no sense how. Yes the ls do last a lot more miles but they have there own problems like filling the intake with carbon and sucking oil from the pve and rusty blocks. So in the end I'm still not sure to rebuild the 455.i know the ls will be cheaper to rebuild. I may put a chevy gen 1 350 in I'm still deciding on which way to go. You can dump the same amount in any engine for it to be what you want. Yes less machine work for the ls and they have a better bottom end. Another reason I did the swap if I blow up the 5.3 I can just get another one cheap. If I blow up the 455 it cost a lot to get a rebuildable core.

Love some SBC, but they dont sell brand new GM bare blocks anymore. You have to buy a $3300K Dart block or whatever if you want a new block.

Built a 400 hp chevy 350 for $3,000 to throw in my 68 Skylark direct bolt in just had to do chevelle motor mounts looked at LS swap stuff way more $$$.

SBC all day for me and FYI is not an ls if it's not all aluminum block and heads not just heads and iron block dont work that way ls fans 😂😂.

I still don’t get the point of swapping to LS engine. You have to swap that plus the harness ECU computer and bunch of other stuff, on gen 1 engines everything is so simple. I was about to put an ls on my c10 but instead i went with a crate 454. Easiest swap ever

Where do you buy car parts this cheap? I have never seen an LS for under $2000

I put a Corvette 327 in my square body I’m just old school I guess even though I’m not that old lol 😂

Definitely not biased at all! But i know an LS guy when I hear one 😂

If money is no problem, the LS is better. Street and race are two differentt environments.

I did a running driving lq4 in my 84 cutlass for $1400. I did not rebuild the engine tho

You can build a 383 stroker for $1800 for everything.

Do your own mounts

You are way off on the Ls And I have ls swap camaro Standalone wiring harness $250 My computer was $100

YUP! That's the bottom line!

Small block all day!

The reason people go for LS is they’re cheap, readily available, but most importantly, they can handle a lot of power, reliably, through forced induction in 100% stock configuration. Skirted block with 6 bolt mains and factory heads that flow better than most aftermarket SBC stuff. You can buy a complete iron 6.0, intake to pan with harness/ecu, toss in a Cam and springs. You have an easy 500 crank for well under $2,000

How is a radiator 3x more for an LS? Heat is heat and hoses are hoses, dude.

I WOULD NEVER SWAP AN LS INTO AN OLDER CLASSIC, I SPEAK FOR THE SAME GROUP OF GUYS THAT WOULD NEVER LOWER A 4×4, NEVER PUT 20" RIMS WITH LOW PROFILE TIRES ON OUR TRUCKS OR HOTTODS.

Why didnt you talk about trans. Assume you have th350, its just not going to get abused over 400. If you want 400 a 6.0 drops in with minimal effort with a 4l80 for 1200 low miles on both. Mounts are like 150 200 for the trans mount, already comes with harness and ecu and you're over that 400 spot. Not to mention, make 400 and get 24mpg at the same time lol its just not the same. Junkyard life

You're ignoring the fact that 1) the LS can be carbureted to eliminate sensors 2) if you're buying a used LS it usually comes with the computer and harness. 3) the radiator in your current project will probably be fine with the LS since it runs cooler. where are you getting all this money for machine work on an LS? A simple tune on a truck motor will hit 400HP without machining or headers. I mean, yeah, if you want to go stupid and buy the most expensive crate motor LS then yes it will be expensive. But you're being disingenuous by mixing the most expensive options with a used motor. The other consideration is your SBC will get 8-10 mpg at 400HP while the LS will get 18-20

The funny thing is most of these new generations don't know how to work on a carburetor

I'll stick with my 406 s10 swapp.

Straight air intake way better.

Your math is wrong. you lowballed the sbc and highballed the LS (by accident right??) sbc $4775 - LS $6450. ......$1675 difference (and the LS does not need all new sensors and harness) Then in the end you have a farrrr better and more reliable motor with the LS

My guy an engine complete at the junk yard is 400 bucks that means COMPLETE ecu harness accessories and all sooo what are you taking about

In a square body Chevy you use a 1987 tank

ls

Trick flows aren’t $1200 try more. A lot more. You can get 400hp easy with factory Vortec heads. So take that price off the board

i just put a sbc 355 650 hp in my 81 gmc for roughly 3000$

Going by the comments it seems you are full of it , sorry just an observation

Dam you totally don’t know prices on LS swap.

LS engines are not as fun to tinker on in a classic. Take this from a guy that LS swapped his chevelle. Then once gou get it in there you realise how ugly it is then you spend another 1k to try to get it to look halfway decent. Really it all depends on what your goal is.

What about mpg

This is a good example of a guy who never ls swap anything just an old school hater like 650 for 7 sensors on what planet are you getting these numbers from

These prices are accurate, assuming you are an a$$hat and arent doing any of this machine work yourself. Sux to be those guys.

The boomer mentality in this video is crazy.

LS is expensive and risky. If it's just a cruiser buy a 350 crate motor and be done with it.

Crazy how much bad information there is these days

You lost me in first minute of the video.....Ive done both on many cars, hp per dollar the gen 3/4 ls is waaaay cheaper. Under 1200hp LS wins the price per hp by alot. Over that it all becomes about the same. If it cost alot of money for you to swap a ls into your car it was by choice...because you bought parts for beauty or personal preference reasons. transmission mounts are same because the transmission is the same. Because the 4l60 is the exact same as a 700r4. motor mounts are same because you just by and adapter plate for like $40. I mean you literally told me you dont know shit about ls swaps in the the first minute of your video. And yes you can quite literally go to junkyard and buy a pullout for $200 5.3 that makes waaay more hp then a stock gen 1 anything. So you are already ahead of the curve by like 100-120crank hp. You have to buy a whole top end package to compete with a STOCK 5.3. And thats not even the best ls engine to get. If someone is starting off with say 6 cyl camaro/nove/whatever or a even a 4 cyl/302 foxbody. The ls swap is waaaaaaaaaay cheaper then throwing a sbc or 351 in the fox. And stock for stock itll be way faster. Youd have to throw an extra 2-3k at the older motors just to maybe keep up with the stock 5.3 with a small cam. 6.0 ls its not even fuckin close....and the used parts for ls family is HUGE...

Don't know how to adjust your lifters properly.

It's clear that you have absolutely no idea what you're talking about. For $6500 you can take a junkyard LS and push well over 650hp, realistically probably closer to 800hp. Sorry old timer

Do your research before you make a video.

Your math ain't mathin'. You're comparing making 400fwhp in a 350 to the cost of LS swapping a vehicle? 😂 What about the guy that ownes a 2002 chevy Silverado that wants 400hp al he needs is $500 cam kit and a tune. If he wants to spend $4500, he can have 650hp at the tire. You ole boys will do anything to keep your carbureted 350's relevant

Old school is the best fu....k LS motors

In a square body Chevy you use a 1987 tank for efi a 3 pin heat temperature sensor oil sensor adapter
