Out with the Small Block and in with the RB. What do I need?

IMO you need to first find a donor body for your new engine......fix/rebuild the matching number engine and leave the H code car an H code car.......

I am probably not a huge hit at the Mopar shows.... Truth be known I would put a V6 Drivetrain in it out of a Buick GN but that would probably get me shot lol....
