No problem.

1965 was the year when passenger car 427's changed from center oiler to side oiler. Because of the relocated oil passage on the driver's side the motor mount bolt pattern is slightly different if you are talking about a side oiler. Center oiler 427's won't be a problem if they are 1965 or later.

The 1968 Cougar GTE had a special motor mount (block plate portion) to allow its side oiler to bolt in and that part will work on 1967 - 68 Mustangs also. However your chances of finding one are about the same asyour chances of finding out that Bill Gates is a long lost cousin.

The real answer is that you can fill in the lower hole on your driver's side 390 block plate by welding in a plug. Then you have to redrill the hole in the proper place. It is not a hard job.

1965 FE heads have only the up / down exhaust manifold bolt pattern so 390GT manifolds won't work. Hooker makes a good set of headers that will work on either pattern. FPA also makes some great headers.

Everything else bolts in place. The 390 and 427 use the same flywheel and the harmonic balancer from either will work although the 427 piece is preferred due to its heavier weight.
