My 67 GTO just arrived on Saturday and [allegedly] it has a fairly fresh 350 pontiac but my plans call for a very streetable 500HP so the 350 will probably have to go. My father had a 67 GTO, 400/360HP, 4-speed, and drove it daily from 67 until the mid 80's so it was inevitable that I would get one some day. I have had and still have a 69 Camaro and a couple vettes but this is the first Pontiac.

I apologize if these questions have been beaten to death but here goes:

I don't remember the pontiac engines being physically this big!! How does their physical size compare to the small block and big block chevy?

I had planned on dropping in the GM Ram Jet fuel injected 502 but the 350 barely fits now with the headers.

How does the 455 compare to the pontiac 400 in physical size?

Can you bolt a 700R4 to either the 455 or 400?

Does anyone have pictures of a big block chevy in a 67 GTO?

What is the best choice for headers...as far as fitment is concerned?

Anyone have part numbers or pictures of an aluminum radiator and electric fan installed? I can only find 1 Be Cool model that says "bolt in" but there has to be a universal aluminum that fits for under $600-700!

Thanks in advance!!
