Answer Anonymously What is the diagram and firing order for a 76 Pontiac trans am 455 engine?
250
In 1979 Pontiac did not make available any 455 (cubic inch) engine. The largest available was a 400 4bbl in the Pontiac Trans Am (220 net horsepower). Also the "rocket engine" description was only applicable to the Oldsmobile Division. The 455 Rocket Engine (Oldsmobile) was discontinued in 1977 where the largest engine was the 403 cubic inch Rocket Engine V8 rated at 185 net horsepower available on the 98 (a 350 cubic inch was standard) and the Toronado. It was also sold to the Buick division and available on the Riviera.
The 1987 Trans Am didn't have a 455
Hard to say who's faster once you put in a non-stock engine. Corvettes never came with a 455, but it might be a fun swap.
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.
Not without an adapter for the engine mounts. Without having to buy or make the adapter, the engines that will fit your car without any modifications are the 69-79, any size.....350, 400, 428, 455.
The 77 Trans AM was built before ratings were required. The 455 cid engine got 11 or 12 when run moderately hard and could get 18 mpg when run gently.
There were 1,968 Hardtops and 241 drop tops with a 455 / TH400 trans.
You need to specify which model Caterpillar motor you have. 455 is just a horsepower rating - several models were available with a 455 horsepower rating, to include the 3406B, 3406E, C12, C13, and C15.
yes if you have the Oldsmobile motor mounts. If you are asking if engine parts will interchange....Absolutely not.
