Is there any difference between a C4 that was in a 6 cyl car and that of one that was put into a 8 cyl car? If so what is that difference and can the tranny from a 6 cyl car be built into a 8 cyl one? We are talking about 1964 1/2 - 1966 Mustangs. I know they have the geren dot valve body which is exclusive to those years. Any information would be appreciated. Thanks Tommy
