455 in the GTO.
i think the GTO has the LS2 6.2 That depends on what your idea of a Pontiac engine is. The "New" Pontiac GTO was available with the 6.0 engine. If you are talking about a traditional Pontiac engine, the largest factory offered engine is the 455 from 1970-1976.
Can you bolt on earlier heads/intake/exhaust manifolds.. from a 1970 Pontiac 455 to this 76 455 engine.

There were 1,968 Hardtops and 241 drop tops with a 455 / TH400 trans.
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.
The only GTO that came with a shaker hood was the model year 1974.
No
Yes. A gto is pretty much the same chassis as a chevelle, which was available with a 396, which is the same size and weight as a 454.
