The oil pan is the same "rear sump pan" that would be used in the mustang. You can use exhaust manifolds if you notch the passengerside frame rail and don't mind givining up some horsepower. Headers would have to be custom fenderwell headers. Either cut the firewall to move the engine back, or cut the radiator suport to move the radiator forward. Install traction bars or ladder bars to eliminate wheel hop. I broke two U-joints because of wheel hope and bent a leaf spring. I think a long bed truck would help with wieght distribution and handle better. I made solid motor mounts for my truck.
My 84 long bed Ranger with a 501 stroker went low 12's at 111 Mph with open exhaust manifolds, then 11.4 at 118 Mph with small tube headers. Maybe with a smaller engine the difference wont be as much. At first it had a stock shortblock 429, with a Lunati Special Purpose Solid cam, Stealth intake, Mild DOVE heads, Exhaust manifolds, 2.5" full exhaust with thrust turbo mufflers, 3.55 gears, 750 double pumper Holley, and ran 12.5's at 108mph. Now it has the pump gas 501 with Victor heads, Torquer II intake, 850 double pumper, 284 comp solid roller cam, C4 transmission, 3000 rpm convertor, 4.10 gears, 31x14.5x15 Et streets, and runs 10.57 at 124 Mph open headers and 10.62 through Magnaflow mufflers
. I still drive to the track evertime I race it. I have it in the Car Build up forum if you want more details about it. 1984 Ranger specs
