If you want to stay chevy and can get a 292. or if you don't mind Mixing parts then the 300 would have to be on top. Can't beleave I just said That LOL But French is right They are a tuff motor. I'm not sure all will inner change.(pistons rods stuff like that. But already having a 4in bore should make things easier and being a 12 porthead well making that breath should be even easier as well.
Ps No i won't get 1 I likes my Chevys and it's bad enough I have a 9in. in it. But strange said my cars is to heavy for there GM3rd member.
