The Dart Gt has a 415 smallblock that runs on pump gas from INDY and Edelbrock heads that the neighbor did for me. 2.050 intake valves and some port work, chambers are 62 cc to get 10.2 compression on a pro tru dish piston, victor 340 intake, 750 double pumper . Have you looked at ET wheels? They have a 5 spoke cast center wheel with the polished rim that looks really cool. I saw a set on a car that had to be 15 X 14 at least. So maybe they could make you a set. Jysnflem
