So many facts just straight up wrong in this video.

[@BrandonLeeBrown]

My father ordered a new, 1970 GTO with the 400 Ram Air IV engine and paid a deposit on it. Some time later, Pontiac contacted him and told him the RAIV engine was no longer available in the GTO for the remainder of the 1970 model year. They offered him the 455 for the same price, but he declined. What Pontiac did was hold back the remaining GTO RAIV engines in late 1970 for use in the 1970 1/2 Firebirds. Between my father, the dealer and Pontiac and since the RAIV engine was still available in the Firebird, Pontiac agreed to assemble one last 1970 RAIV GTO for my father's order. So my father's 1970 GTO was likely the last RAIV GTO made.

[@charliereed4642]

Great story

[@JamesBarber-cu5dz]

Awesome, but I'm still disappointed they never came out and offered the Ram Air 4 or 5 455. If only the emissions thing had been held off for 5 more years!

[@BrandonLeeBrown]

@@JamesBarber-cu5dz The performance guys at Pontiac developed a RAIV 428 for 1970. Pontiac wouldn't let them make a 428 for 1970 and a RAIV 455 hadn't been tested and there was concern it wouldn't hold up, or the drivetrain wouldn't hold up, because it hadn't been tested for a RAIV 455. So the RAIV 428 was scratched for 1970, but it inspired the round port, aluminum intake 1971 455 HO. The big Olds and Chevy engines got 2.5 inch exhaust pipes, but all Pontiacs got 2.25 inch exhaust pipes. It might be just as well, as the high performance Pontiac exhaust manifolds didn't make much difference over the standard dual exhaust and the aftermarket Pontiac manifolds that take 2.5 exhaust pipes don't perform any better either. The Olds 350 W31 engine was hand assembled with racing clearances and ran with the big engines, with standard 350 Olds exhaust, which was smaller than what the big Olds engines used. Pontiac tried to get a compression ratio waiver from GM for the 455 Super Duty, to run a higher compression, but GM denied it. Chevy got compression waivers for the 1971 LS6 Corvette and the 1971 - 1972 LT1 and the 1973-1974 L82 engines in the Corvette and Z28. That's too bad the 455 Super Duty couldn't have had a higher compression ratio. The GM limit in 1971 was 8.5:1, but the LS6 and LT1 were allowed to run 9.0:1 compression ratios. In 1970, the Pontiac engines lost a bit of compression ratio and the 4-barrel, automatic transmission 066 camshaft was dropped for emissions and standard performance 4-barrel automatic engines got the 4-barrel manual transmission 067 camshaft in 1970. We blueprinted a 1968 RAII 400 to NHRA specs and the measured compression ratio was only 9.98:1 after all of the blueprinting to maximize the compression ratio. So from the factory compression ratio was actually a bit lower.

[@LR-my2di]

@@JamesBarber-cu5dz And the 455 H/O was NOT produced in 1970, period. The 455 for 1970 was just the Bonneville engine. pure and simple. Buick did likewise for its 1970 GS 455.

[@glennwilliamson3351]

​@@eriklarson9137 Pontiac engines from 287ci thru 455ci used basically the same block with displacement changed by bore and stroke. Oldsmobile and Buick had 400/425/455 and 400/430/455 engine families, respectively. They also had 330/350 (Olds) and 300/340/350 (Buick) engine families which were quite different than the big-inch engines. Also worth noting that until 1970, GM's unwritten rule was no engine larger than 400ci in any intermediate-size car, and that Oldsmobile dropped the 455 bomb in 1968 forcing the other two to play catch-up. Then what did the Rocket Division do but circumvent "the edict" and stuff 455s into the 68-69 Hurst/Olds. Hey, Pontiac got away with it in 1964. Actually Oldsmobile's intent with the 455 was to save cash by being able to build the 442's 400 engine on the same engine line as the 455, using the same crank. That did not work out well for the 442, as the long stroke 68-9 400ci engines rapidly gained a reputation as grenades.

In its first setup I ran a trw w-30 copy grind, O-4B intake, 750 Holley dp, off brand headers, tci 11in converter, original 3.42 axle. In 1987 it went 13.10@107 uncorked on radials.

back in 1979 I bought a 1975 Buick Riviera with a 455 , that was such a nice car. had it for about 6 year until the gas crisis , when you would kick it into passing gear getting on the freeway the speedometer would go right and the gas needle would go left .

@tonyidle7813 as a teenager, my very first car in 1975 was a pretty beat up body & interior Pontiac Grand Prix. That being said, the Power Train was still in great working condition. It had a 455 and man did that fckr have torque. I would stay in one place smoking the tires without applying any brakes, but yes. Speedometer & gas gage would literally go in opposite direction whenever I would pull off from a red light. Even on a normal none aggressive pull off. But it was fun though..Lol.

It’s claim to fame was a significant reduction in weight. It was a two bolt main motor weighing around 667lbs, the hemi was nearly 800lbs. Also, the improved oiling system was added because they were prone to cracking in the lifter valley portion of the block. A well tuned Buick 455 Stage 1 would out run any Hemi or BB 454 with relative ease. But when the Buick 455 let go, it let go! No saving or rebuilding the block.

Then I discovered my Aunts Sky Lark had a 455 package under the hood. She never knew what she had, she drove it 50 miles per hour or less... lol...

But 100% the maverick was supposed to be competition for the VW beetle, datsun 510 and basic imports.

Wow, this brings back memories- thanks random algorithm! I grew up in the back seat of my parent's 1970 Pontiac Bonneville sedan that had a quad-barrel 455 (Dad's first new car with his re-enlistment bonus.) My fondest memory was a time when my Mom led my uncle through town onto the highway to get him pointed back towards Boston (lived in Plattsburgh AFB at the time.) My uncle is a Mopar guy and for some reason he and Mom mixed it up getting onto the highway. That Charger took the early lead but the 455 ate him up eventually. I remember 2 distinct things: 1) a BIG cloud of black smoke behind the Bonneville 2) seeing the gas needle actually moving as I stared at the dash from the rear seat!! Memories!!!

Im really glad to see so many people supporting the Buick. My Dad worked for Buick in the late 1960's, and Early 1970's, so as a teenage boy, with a twin brother, we drove Buicks from the very beginning. My twin brother was lucky enough to find a 1972 solid white Stage 1 car which was just as fast with the decompressioned engine as it was with my dad's 1970 Ten and a half to one engine. I know because I pulled the original motor out of brothers car, and while I was freshening up his original eight and a half to one engine, i put my dad's ten and a half to one motor in it so he could daily drive the car. Unfortunately my brother was dumb enough to sell the car in the 1990's for a steal of $9,000 which when I found out made me sick. I had to build my own car out of a 1966 Skylark with a bone stock low compression engine, because I couldn't afford a Stage 1 engine at the time, and I wasn't about to assume that dad's engine was mine to do with what I wanted, so i never had a Stage 1 that was mine, byt i can vouch for just hiw fast the Buick 455 was, because I rarely ever git outrun by anyone at that time with a liw compression stock engine with absolutely nothing high performance about it, and when I couldn't beat them i went and borrowed my brother's car.

[@jamesslick4790]

"I'm really glad to see so many people supporting the Buick." I only EVER bought 2 NEW cars BOTH were Buicks! And most of my USED cars were Buicks or Cadillacs. As to the "muscle cars"; Buick KICKED it off at GM (TBF Buick STARTED GM in the first place...) The Pontiac GTO often is credited with the whole concept of stuffing the biggest engine into a midsized body car. But the GTO was the THIRD GM car to to that. The Oldsmobile Rocket 88 in the 1940s was before, and the grandaddy was the original GM "Muscle car": The 1936 Buick Century! The coolest bit is the Century was not only available as a coupe, but also as a sedan. Meaning the '36 Century was GMs first "Sports Sedan"! If ONLY Buick would NOW get back to making CARS, I'd be in the market.

That was the only big block I ever owned. Because of Pontiac's wonderful engineering, a 73 455 dropped right into my 1980 Trans Am Turbo. It was also hopped up with a moderate cam, headers, intake and carb. And it's ironic. You couldn't get more of a screaming, flashy car than that era Trans Am, and yet everyone knew it was slow AF so it was a major sleeper. I didn't know you could get so many kills in such a car. It killed a Viper once which was my favorite. Unfortunately it had so much torque it was warping the B pillar of the body, I was afraid it would grenade the TH350 behind it, and I the whole car needed restoring anyway. When I sold it, multiple buyers came forward and everyone of them said they wanted it for the 455 to put in a GTO, which is what it was finally sold for.

@ It had the stock 3.08 gears. It didn't need anything lower. First gear was absolutely useless, and it would easily burn out through 2nd gear as well. If I were to drag race it on the track it might have been different, as I could have used slicks.

[@nathancarpenter7626]

​@@eriklarson9137That is absolutely incorrect. Oldsmobile does indeed have small blocks & big blocks. The small blocks have a shorter deck height 9.33in vs 10.625in on the big block. So the small block has narrower intake manifolds. Than the Olds big block. They also have smaller main & rod bearings 2.5in main & 2.125in rod. Vs 3.0in main & 2.5in rod as used in the big block. The connecting rod lengths are also different 6.0inch in the small block. Vs 6.735inch in the 455. Only the bore spacing is the same so they could manufacture both on the same machinery. And use all of the same assesories between them to save production costs.

[@BeverlySeverence]

I owned a two door 1973 Pontiac Grand AM with the 7.4 litre badge on the tail. That's the 455 cid motor with a 4 barrel carb and dual exhaust. This was a special John Mitchell designed car meant to compete with big Euro cars like Benz, BMW, Jensen, and some Italian GTs. Less about straight line performance, this 455 could set you back in the seat and cruise all day above 130 mph, as I experienced driving through Colorado, Wyoming and Montana. The Grand AM was certainly muscular, but it had a euro ride, making cornering and control priorities...and it was a gorgeous, shapely car, unlike the ugly Olds and Buick.

[@janfswedane]

The Buick by far... It's the newest of the three released in 1967 as the 400/430. It's much lighter than the others app. 50 lbs heavier than a SBC. And in 455 Stage 1 form it delivered 500+ ft/torque. Oh yeah, It's also the only one beating a Hemi Cuda..

The Buick 455 Stage I was a Hemi killer, the combination of light weight and 510 ft/lbs of torque at 2800 rpms made short work of moving heavy weight.

You mean the Olds "Ram Rod" 350 ? I don't read enough about them. Yeah, as much of a Poncho head as I am, I've learned a lot over the years how good the Buick was , in several ways. As torquey as the Pontiac is (the Car Craft comparison from around 2001, they couldn't find the true torque peak on the Pontiac, because the dyno readings started at 3600, and it was already coming down a little), and yet there was th he 455 H/O in'71 & '72, and the even better super duty455, the even longer stroke Olds 455 had torque, but didn't make hp at high rpm, and didn't like to rev. Not to say its like a Cadillac, or a 460 Ford truck motor, but it came in last among the 455,455,454,460,440 comparo

[@TS1964]

Rarely did a Buick beat a Mopar this is why the Hemi dominated and is still available today. GM vehicles are heavier not lighter. The Hemi was not really a daily streetable engine. BTW ...

[@lawnboy8401]

​@TS1964 I never remember Hemi cars doing much in stop light races. They always bogged off the line they needed to rev to make power. Now on the quarter mile they would often take over the lead towards the end when they were at high RPM. The 440 6 pak was the ticket for stoplight racing. It offered off idle torque.

Guys in the Vette looked over and asked, what kind of Cutlass is that? I said it’s a Buick. A Buick!, the guys replied. We all went HD together.

This is all from memory, so some of it could be wrong. Prior to 1970, Pontiac was counting on the introduction of their Ram Air 5 400 in 1969 to be their Super Bowl street engine. There was also a 428 version in develpment, for drag racing. I saw one article many years ago, where somebody got ahold of a 428 Ram Air 5, switched to a bit of a bigger Holley carb, installed it in an orange Firebird, and dyno'd at at just shy of 500 hp, running in the 11's with a 4 speed. Unfortunately, it was cancelled once John DeLorean was moved to Chevrolet, and there wasn't enough money left, according to what I have read, to develop a really great top performance 1970 455. Pontac was compelled to keep the Ram Air 4 as the top performance engine for that year. The ultra performance Super Duty 455 engine finally came out in 1973, but it was a few years late, it would have been as good as any in 1970, with high compression and Ram Air 4 cam.
