The crank will most likely work. The cases will have to modded not only for the bore but the different rear stud location and cyld size. IMO the 39s will work fine, after that there isnt much that you have that will transfer. Your looking at
cyld, head, domes, hardware, intake, reeds, pipes, and Id assume that you will need some additional stuff on the clutch side depending on how quality of a build your 465 is.
