I just got a 5.0! the only thing i dont like is that it's automatic, so I was gonna take the manual tranny from my 4cyl stang and put it in the 5.0 What parts are not interchangable and what do i need to buy new? The bellhousing? I was looking at the centerforce dual friction clutch to replace the stock one, will that and other performance parts work on a 4cyl tranny? What's a good shifter?
