wut wuld i need to do to swap my 302 out of a 89 mustang to a 351 m? i basically just need to know wut i need to do.thanks alot

Motor mounts are different, transmission is different, the motor is a whole lot wider and taller. I would say you are going to have a ton of clearance issues. Why an M motor??? A 347 stroker kit in the motor you have with a good set of heads will be a better set up and probably less costly in the long run.

A 351-C will bolt in as it uses the same mounts and bellhousing bolt pattern as the smallblocks,probably wont be too much trouble as 460s can be fit in the fox bodied stangs with minimal trouble.
