My exact thoughts, Murphy's Law always applies.

My neighbor had a stage 1 fully black, in the late 80s I use to drool over that car, I’d like too get a 71 vette and build it to L88 specs. Any start on your new car?

I TOTALLY agree. Back in high school in the late 70's a buddy of mine had a Riviera GS with the 430 big block, I swear it was hard to tell from the 455 it ran so good. Big block Buicks were easy to build into torque monsters. I had my uncles old '63 Lesabre left to me, that old Wildcat nailhead ran pretty good as I recall, had to burn premium in it tho or she would ping cause it had 10:1 pistons.

430 should have been in every Regal GS standard from the jump. they were certainly Great engines in the Rivera GS.

w41duvernay should have been prioritized over the 350 that’s for sure

The 350 was an improvement over the 340, not simply because of 10 extra cubes. The real advantage of the 350 was its tall narrow ports, which gave the engine a broader torque curve. Compare them and notice how remarkably similar the ports of the LS heads are on the current small block Chevies.

@@oswaldmontecristo1035 I agree. I built a Buick 350 for my 1965 Skylark with 2:78 gears that ran neck and neck with my brother's 1965 Skylark also with 2:78 gears that had a stock 1971 Buick 455. A 1970 Buick 350 and a 1971 Buick 455 both had the same horsepower: 315. But I still like the 340 for its fuel economy and smooth operation. Any and ALL of these engines are better than a Chevy from any era or displacement, small or big block.

best mod would be a set of aluminum heads or stage 1 heads. the 430 doesnt gain much from boring over and idk if you can go to a 455 on a 430. 440 is about max you can get them and not destroy the block.

Trent Robey + I trust you that this car miss you. You have beautiful memories :) My grandmother was also amazing. Have a nice day Trent !

yes...the 340 buick v8 is the buick 215 bigger brother!!

Garand Man Was that the 215? I had a 300 in my 66 GS that I thought was asll aluminum?

The Buick engines went iron block for 1964 and iron heads for 1965, so no, your motor was an all-iron derivative of the same engine

Shelby wanted to use the aluminum 215 in the Cobra but GM didn't want competition for the Vette. He had to settle for Ford. Mickey Thompson entered a stock block 215 in Indy.

Garand Man lmao!! Shut up

Me and a friend did three MGB conversions with that engine. It was 100 pounds lighter than the stock four banger. An olds 305 crank would fit with 327 rods and you could get 300 cubes and 300 HP.

I had a '90 Riviera...I loved it. Only wish it was rwd. One of my favorite things was the license plate slot...never seen that before, or since. The digital dash was also really cool. That old 3800 N/A was a savage and ran great with well over 100k miles on it. Miss that Riv and wouldn't mind owning another of a similar year (90-93). Hope ur L67 swap turns out awesome, I'm sure it will.

At the time sure but nothing past 210-220 horse just loads of torque. They didn’t like to breathe very well.

I had that 350 in a 74 Buick Apollo. With upgraded carburetor, distributor, and true dual turbo mufflers. That thing turned into a beast. I didn't race it often, but was truly respected in my hometown. I miss my Buick.

@@theeoddments960, We had a remedy for that engine not breathing with a simple fix. We would unscrew the breather cap top, flip it upside down and screw it back. Hence giving us about two inches of clearance, therefore sucking in cooler air to generate more horsepower. And that little 2bl carburetor loved it. Outstanding engine that 350cid was.

I drove a ‘73 Centurion convertible for nearly 20 years with the 350 four barrel. Smooth and powerful for a very heavy car.

A stock 75 car being "very fast"? You must have souped it up.

I like nailheads, but the 430 was probably the best Buick v8. They were light too, making them great for hot rods/sleepers.

You're right Bro. I have a 69 Electra hardtop coupe and I've beaten plenty of cars during my younger days. It's still hard to believe.

The GS400 through '66 used the 401 nailhead, superseded for '67 by a 400 cube version of the all-new 430. The 400 was quicker in a straight line, but the 340 gave the A-body better balance and handling. On the whole, I'll take the 340 or even the 300-4-barrel "Wildcat 355" in my Special.

Amazing how people are so misinformed about Buick engines and their derivatives. 300-340-350 are all of the same family and are small blocks; 300" has a 3.75" bore and 3.4" stroke;. 340" has 3.75" bore and 3.85" stroke: 350 has 3.8" bore and 3.85" stroke. All of thee are derived from the 215". In fact, a 300 crank and 300" bore can be used in a 215" as well as its heads that gives it larger ports. 350 had different intake-exhaust valve order due to major revision of the cylinder head that featured a tall port. The famous Buick 225" V6 was also derived from the 300", sharing its pistons, rods and valve train components. The 231" in newer v6s had the 3.8" bore the 350s had. 400-430-455" engines are big block Buicks and share no components at all with their small block cousins. Their arrangements are similar, like an inflated 350" motor, but rods, pistons, block and valve components are not interchangeable. Both small and big block Buick V8s have the same type of external oil pump arrangement and internal oil passages in heir blocks, and have similar oiling issues at high rpm's. Big block engines are more susceptible in oil issues as their extra large crank journals act like pumps to force the oil back against its pressure into the block Small block Buicks have torque similar to other brands big blocks. Big block Buicks couldn't be beat for torque. 510 ft.lbs. at 1800 RPMs was the most out of Detroit before the current generation of LS motors and Hellcats hit the scene Both small and big block Buicks have a distinct weight advantage over the competition. All iron 300-340-350 engines weigh in at 450 lbs. 400-430-455 series big blocks weigh in at 600 lbs, or about 25 lbs more than a small block Chevy.

2800 rpms*

I was going to say the same thing , till I seen your comment , wonder why it wasn’t mentioned always thought the 400 was a bit more popular than 340 .

Johnny Wrench if people think that the nailhead’s head design was a design flaw, they’re absolutely wrong. The nailhead has tiny intake ports and valves for instant and effortless torque. Plus way more efficient on fuel than the contemporary hemis in Chrysler products. Makes a good snarl in any car Buick ever put it in too.

BrewBlaster Hi how you doing . I had a 1966 olds 425 punched out 40 over bringing it to 442 C.I. that was pushing over 500 H.P. I used the 70 w-30 stick grind cam I had to have it custom ground becouse of the 39 degree bank angle and edelbrock torker intake and holly carb. There were a few other tricks as well it was a match made in heaven break loose tork city with a 67 Buick 400 turbo reverse manual valve body and 4000 stall converter...rear end was 456:1 shimed posi.

One of my best friends had a 66 GTO that he bought with a 425 Olds motor in it and it was soooo funny when he trashed other GTOs XD....BTW...what car body did you have this motor in? I know you said Buick, but it looked like you were talking about parts and not the car itself.

I worked at a Olds dealership, drove lots of Oldsmobiles, nothing that Olds made would run like a 425, NOTHING !!

You’d be better off to get a corolla

I had a 69 with the neighbors daughter in my 426 Hemi Big block Buick 350 2 barrel

Don't you hate that?

I seen one today. 65 wildcat

That is 1961 - 66, but if you replace the rocker assemblies with the 53 - 60 version, that problem will be no more.

Wrong. The 340 was the first generation small block that was introduced in 1966. It was a derivative of the 1964 300 motor but the 340 and the 350 are both the same color and look pretty similar. Best way to tell the difference is the staggered exhaust. Nailheads were phased out in 1966 where the 340 was made till 68.

I have a 62 Skylark with the 215. Nice little motor

@@professordickweed880 PROVIDING you don't think "100% Dow Guard Antifreeze" means using it unmixed.

Felix The Cat stage 2 was cut off after 1971 with leaded gas being phased out and lower compression and was never introduced OR dealer installed. There are less than 5 examples.

@@theeoddments960 Had no idea talk about a rare monster. My first car was a 71 skylark but just a 350 but was still fast. beautiful car it was metallic green. thx

The 340 was found in the 66 and 67 Buick Special. 401 and 425 nailheads were mostly in the Wildcat's and Rivieras with the top dog being the 360 hp, 465 ft/lb tq dual 4 barrel 425. Likely under-rated.

Thanks very much....and you said 425 Rivieras...did they share a motor with the Toronados?? Okay maybe that was before the Toronado...sorry.

The Nailheads were only in buicks, the 425 was in every Riv and a few wildcats i think. Oldsmobile had a 425 and Cadillac did too but they were different 425's. The 264,322,364,401,425 were all nailheads. Nailheads were available in every buick from 1953 to 1966. Quite phenomenal engines. in 1964 Buick's R&D put a small turbo on a 425 and it made 708ft-lbs of torque at 2800rpm... With a turbo about as big as a cantelope and no intercooler.

I had a 66 Le Sabre with a 340 4 barrel.........

Also had a 67 Wildcat with 430 4 barrel

Ah yes, the days before the corporate V8 (Chevy small block) in the middle,late malaise era of the 70's. Since each 350 had its own brand's block, they all weighed differently and had different horsepower/torque curves. Each division had their own style A, B and X bodies that utilized them, so they all had their own distinct spring rates and shocks to refine their rides. That is why they were each more distinct from each other. A Cutlass was different from a Skylark that was different from a Chevelle that was different from a Lemans. And a Nova was different from an Appollo that was different from an Omega that was different from a Ventura

Pontiacs, like Buicks and Olds, did not have big block/small block. They had large journal/small journal, which is an interior feature. So they all looked the same on the outside, except for casting numbers, paint color, and decals.

Not quite right, Jack. Both Chevy and Buick were small blocks with center to center bores in common with other small displacement engines in their respective family (215-300-340-350 Buicks) and (262-265-283-302-305-307-327-350-400 Chevrolet). Neither the Buick or Chevy small block engines would interchange manifolds, cams or heads with their big block brethren, unlike the Olds and Pontiacs did with theirs. All these different displacements were obtained by changing bores and strokes. There were some journal sizes variations and deck height changes, and rod lengths from the 215 to the 300 and from the 300 to the 340 in the Buick family.

That was only p0ntiac. Buick, chevy, and olds had distinct SB and BB engines.

Oswald Montecristo Trust me those “little” changes made all the difference with the personality of the engine. The small block Chevy is a high rpm screamer and the Buick small block is a small journal torque monster. Buick is done at about 5 grand. I should know I’ve got a 72 skylark myself. You can’t really go passed 320 without losing that torque way down low but if you built both engines build wise the sbc you’d get 350 horse 360 torque. Buick you’d get about 300 horse and 420 torque. The stroke on the Buick is bigger than a small block 383 stroker, so that says a lot.

This video title answers that one. A V6 is not a V8, Cadillac's V8-6-4 notwithstanding, but the Caddy V8-6-4 couldn't withstand much of anything, and most were converted to non-modular operation under warranty.

I shall correct myself. 57 to 61.

they made both. nailheads came in 264,322,364,401, and 425

Yea they did! Available for '54 and '55 in the Special only. It was a small bore 322, 3 5/8" verses 4" on the 322. The 364 had both a larger bore and longer stroke than the 322.

Yes they did make a 264, for the 54 - 55 Special. It was an underbored 322.

The 430 produced 370 horsepower.

a 66 wouldnt have a 430 and a 72 electra wouldnt have a 401 from the factory. 66 should be a 401 or 425 and 72 should be a 455.

no longer made

350 Buick was not part of the 400-430-455 family, which were big blocks that superceded the famous nailheads. It was a small block derived from the 215 aluminum motor (215-300-340-350)

You're thinking of pontiac. SBB, and BBB share nothing and are not the same. SB and SB share parts, as do BB and BB, but not SB and BB.

“Research people it’s not that hard” shut your stupid ass up lmao like you’re sum Buick expert yourself

Best comment ever #dead

What's wrong with the buicks? They're literally just better stronger versions of the chevys, olds, and pontiac.

90% of them are ugly. sorry bro.. That's why i have the only have a 70 lark. an a 86 regal.

+Bryan Averette You've never seen a Wildcat? Riviera? Skylark? Really?

I just said i have a 70 lark.. an yes i seen a wildcat an a riviera.. i stand by my statement.

No, GM produced buick nailheads in 1952. the 1953 buick had the option of the 264 nailhead or the 322 nailhead. The straight eight was not being produced in 1953 so there were only nailheads. CHEVY didnt make a v8 before 55, buick did though.

Olds had a V8 in 1949. Buick in 1953.Chevy had one back in about 1919. .

That's not only not right. It isn't even wrong! Oldsmobile-Viking in 1929-31. I believe Pontiac-Oakland did, too. The early Chevy of the teens is well-documented.

Just for youtube Wrong. 1953 Buick Specials had the last of the small straight eights. The V8ths weren’t an option. The Supers and Roadmasters had the V8’s.

Just for youtube actually Chevy had a V8 in the 1910’s..... about 1918 or so....

Are you serious? It was known far and wide as an outstanding engine.
