Technically, Pontiacs are not “numbers matching”. The only serial number is on the body/frame & 4 spd cars on the trans. The motor does not have a s/n on it just a two digit code & date codes.
Personally, I think it would be a sin to put a chevy motor in it. Fuel Injected Pontiac with twin snails on it would be sweet.
Glad to see another classic GTO on the site. Good luck with it. Keep us posted with pics along the way.
Black '65 GTOs are gorgeous. Black with a repro (porno) red interior FTW.
Fuel injection on classic motors is sweet. I have a mechanical Hilborn setup that I would love to convert to EFI & use on mine. Problem is that it fits the earlier (pre '65) Pontiac heads, not the modern ('65 & later) heads. When I build my 455, I’m running the Edelbrocks that are based on the later heads. If I can locate the proper flanges for the later heads, I will do it.
Pewter…Is that motor out of the red car younz had?
