I've recently found a local guy with several Pontiac engines.
I believe the 400 would offer a stronger block, but I'm not sure if this is really an issue for me.
He has so many parts, I could pick date codes, heads, intakes and carbs.

This will be for my 79 Grand AM 4 speed car.
Also, I'm not sure if I should even keep the Saginaw 4 speed or go 5 or 6 speed...
I'm starting with the frame, so I have some time, but would like to lock in on some of these parts.
Any suggestions would be appreciated.
