New to forum. My son had a 1971 Maverick given to him for dirt cheap. 250ci with 3 holes in the side a a few parts laying throught the holes. Someone said it's a Grabber, but I don't know exactly how to tell. We'd like to put a 302 in and autocross it. Just fun. Anyone have any comments or helpful suggestions. I've done a couple engine swaps before, but any suggestions are always appreciated. The 302 isn't my first choice, but he wants it. Thanks!
