Message: Any one do the swap? I am taking a hack at it and need some help with the headers. "A" body fender well headers may be the closest fit. I have 499 inches in a 72 400 block 10.5/1 for the street. I have a 727 from a B body and a B body 8.75 rear with 3.23. The B body 8.75 fit right in no mods 30X10.5 buns.
P.S. not the cold weather block 400.
