360 C.I. into '65 dodge dart a-body?

And of course the transmission doesn't bolt up to a 360. THe 65 driveshaft is a ball and trunion style and should be replaced with a standard u-joint style shaft. The 7 1/4" rear end will last a few weeks behind a 360 and should be replaced with at least a 8 1/4 from a later model car. The 8 3/4" rear is recommended. You sure you still want to do this swap? I could sell you my 66 Dart and it already has a HP273 and a 4 speed and 8 3/4" rear end.
