So Hypothetically.....(318 swap)

Oh boy,this is gonna take a minute,you wont need a k frame swap,you will need v 8 centerlink for the steering,v 8 engine mounts and v 8 transmission and v 8 gas pedal and related parts,and v 8 for early a body exhaust manifolds those are definately specific but I think later v 8 manifolds could be used if you have an artist for an exhaust guy.you wont be needing a drive shaft if you stay with the 904 trans
