As far as going in the engine compartment and bolting to the transmission, and Pontiac, Oldsmobile, Buick engine will work. You may have a duel pattern transmission which would allow you to use Chevy also. You would have to look to know. Where the trans. bolts to the engine there will be two holes side by side. Al GM except Chevy are the same as far as bolt pattern. Any motor will work, it's just a matter of running the Plumbing, electrical and exhaust.
.The 1978 Pontiac Trans Am engine oil dipstick can be found on the right hand side of the engine. The engine oil dipstick will have a yellow handle.
The 1978 Pontiac Firebird Trans Am engine oil capacity is five quarts. The 305, 350, and the 454 cubic inch motors all had the same motor oil capacity.
No, Pontiac stopped 455 production in 1976. They are easy to swap in though.

To get a 400 Pontiac Motor in 1979, you had to also get the 4 speed. Pontiac last manufactured 400 motors in 1978 but saved some from 1978 for use in the 1979 model. Those motors were used in the 1979 4 speed cars only. 1979 Automatics had the Oldsmobile 403. You could also get a turbo version too. All of which could come with auto trans. I worked on many of these at the Pontiac dealer.
