well, dunno how much you want to spend or what you have in mind, im bagging my 47 and building it from the ground up and am stll using my stock rear housing, swapping out pumpkins, if you want higher highway speeds decide what trans you want and go with a diff rear end, im still using my 235 with a saginaw 4 spd and the rear pumpkin swap is a 3.90 rear gear, so im lookin at 60 tops highway, but im all about going low and slow, hahaha, any more questions feel free to ask!
