It's his car and he can build it however he wants. As far as helpful information, I think the best was sending him to Butch's website ( a supplier who not only advertises on this site but also sells mounts for the SBC install). As far as saving an old Mopar goes, anytime you keep an old car running regardless of motor choice you have saved it from the crusher. In the 50's and 60's guys were putting Cadillac, Buick and Oldsmobile engines and Hemi's in anything as long as it made the car go faster and looked cool. I remember when people were putting big block Chevy's in early GTO's. I couldn't believe they were doing that. I've been on this forum almost 20 years and most times I say nothing because a question has been answered before I see it. The purpose of this forum is to share information. Bottom line in my opinion is if you can't give a constructive answer, don't answer at all.
