A couple of other things to think and watch out for are, oil pan for II 302 is mustang II specific, most other 302 pans wont fit the II. Also 302 built after 1980 have a 50 oz. balance, and pre 80 have 28 oz. balance. if you are using a pre 80 c4
tranny and a 302 81 and up then the flexplate must be changed to 50 oz, which brings out another problem, which is that mustang II c4 is specific and comes with a smaller bell housing which in turn requires a smaller flexplate. Mustang II flexplates can be found at Art Carr Performance. So do your homework well before attempting this swap. I have done several and learned the hard way. Motor mounts for a II are definately hard to locate, but there are at least two members from the Mustang II Network that do sell them. If you need more info on the swap, email me and I will try and help you through it.
