There were 1,968 Hardtops and 241 drop tops with a 455 / TH400 trans.
The firing order for a 1970-76 455 should be 18436572 Enjoy!
The only GTO that came with a shaker hood was the model year 1974.
The Pontiac 455 came in 3 versions. Base, High Output, and Super Duty. The base 1970-71 engine produced 200 hp and 455 lb/ft torque. The Super Duty 1970-71 engine had 335 hp and 480 lb/ft torque. Power was reduced after 1971. The Buick 455 came in 2 versions. The 1970 Base engine had 350 hp and 510 lb/ft torque. The Stage 1 engine had 360 hp and 510 lb/ft torque. So as you can see the Buick was the more powerful engine by far.
Yes i Don't know how many Oldsmobile Cutlass 455 were made but it wasn't as many as the Oldsmobile 350 Rocket. So it was a big plus if you had the 455 engine because it wasn't as many around.
No
It had a 455.
Zero. Pontiac never installed the 428 in the GTO. GM had a corporate ban on engines larger than 400 CID until 1970. In 1970, the 455 replaced the 428. ALL GTO's built from 1964-1966 came with 389's. ALL GTO's built from 1967-1969 came with 400's.
a 455 you need to buy a engine mount kit from national parts depot or just make it easy and weld them in place. I put in a 455 into a 1970 lemans, the car never came with a 455 but i had no problems mounting it in. Attach the motors mounts to the frame mounts put in the engine check and make sure it is level attach it to the trans then weld away yoy will love the 455 its a beast.
