If it's automatic, no.
No, Pontiac stopped 455 production in 1976. They are easy to swap in though.
it is behind the parking break.
Yes both the 350 and 305 will fit,most firebirds came with 350 in the 1976 year as long as you have the correct mounts with a little work they will fit,try going to www.thirdgen.org and posting the swap in the forum alot of people will give you there info and alot have done it before
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.
no less than one and no more than a million
There is a 1976 Pontiac Trans am on eBay for a good price that you could look into. I would suggest looking into craigslist and seeing what is available in your area.
180 bhp (183 PS/134 kW) at 4500 rpm is the power of the Pontiac phoenix 1976 engine and its maximum speed is 124 mph.
Either a 3-speed automatic or 4-speed manual
Get the motor mounts, trans mounts, transmission, radiator from a 1976 Malibu or Monte Carlo and swap them in.
The engine block from a 1976 Pontiac Astra was made out of aluminium.
Depends on the engine and transmission
