no longerhave a 64 valiant was 6cyl stick. want to put v8 360 383 in it. W hat rear end will fit this without having to cut it down. Doesn't have to be a mopar as long as it doesn't have to be cut. Have any suggestions. Have other questions but will ask more later. Thanks

 

You most likely have the 7 1/4" rearend. Your direct bolt in will be a A-Body 8 3/4" rearend.
