I have a 7.5 with a C6 from an 89 f250, and I want to put it in a 79 mustang. The 79 has a k member and 8.8 from an 89. I went down this road once before, but back then we spent the money for the right headers and motor mounts. I'm mainly wondering if anyone has tried this using the stock truck manifolds and if they fit okay. Obviously not ideal but this project is LOW budget.
