My Fiance's mom has an old mid 70's Pontiac 400 motor with the 6X heads on it sitting in her backyard. It's a bit rusty on the outside though. I pulled the manifold and it looks ok on the inside, and it should be rebuildable. Hasn't been in a car for well over a decade.

A guy I work with is looking for a 400 to put into his 84 T/A. What do you all think a good price for the motor would be?
