I recently asked about some casting numbers from a fe i bought recently that was in pieces and got some great info. This time I have a question about a 390 that my dad had bought about four years ago. Its a 390 out of a 65 t-bird. I want to put it into a project 57 f-100. The thing is that I want to put a 4 speed toploader behind it that was behind my 429 cobra jet that is in my 55 f-100. My question is, Will the flywheel from the 429 work behind the 390?
