My dad is doing an engine swap in his 57 savoy.From a 301 v8? to a 64 318.Original pushbutton 2 spd.Using a 3spd pushbutton.Will have to put in a floor shifter.Are there any motor mount differences,trans mount differences?Before the trans issue we noticed that the crank flange sticks out further on the 318 and the 301 had a strange hub setup.That is why the later trans.Any help would be appreciated.
