Hello all, new to the forum and have a couple questions. I have a 1967 Cougar that came with a small block. I am in the process of swapping in a 390 and am wondering what kind of motor mounts I use. The block is from a 64 thunderbird. I believe the motor mount bolt pattern changed in 65 but not sure. I was also under the impression that the frame mounts were the same for the small block and big block in 67 cougars/mustangs, is this true? Pictures would be very helpful and thank you in advance.
