Harness , diff , motor and box just to start
you would be better to add forced induction its cheaper

It really is a lot cheaper and easier to add forced induction... you'd also have the benefit of saying you "only have a V6" before you dust Camaros.

...but if you're intent on the swap, you'll need the engine, transmission, wiring and computer, driveshaft, rear axle, and springs.

Any reason a 97 cougar 4.6 wouldnt go into a 97 mustang that had a 3.8?
