Very cool build you have going. I have a 91 sport that I built into a race truck. Mine has a 11.1 compression 2000 360 magnum and 904 engine. Best pass so far has been 11.24 at 117 in the 1/4. I used 5 lug rotors from a 87 dakota on my 91. On the rear axle I used a Ford 8.8 from a 97 Ford exployer. It is a little narrower than the factory 8.25
