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.

What is the biggest engine you can fit into a 67 Pontiac Gto?

a 455 you need to buy a engine mount kit from national parts depot or just make it easy and weld them in place.

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.
