396/375 aluminum head fits as natural B I believe, and Iron head as natural C. Neither are bad combos IMO. I started to go the 375 route a few years ago but opted to go oval port for lower rpm and maintenance. Weibes chassis parts worked very well but from what I understand he’s no longer making the stuff. The Dick Miller parts work very well too. There are a few guys running the ‘70 402/375 combo that I’m sure could help you out. As for wheels, I run 15x10 with 5.5” backspace. They Center in the wheelwells near perfectly
