[GOODOLEBOY84]

Well im about to start my build so i thought i would see what yall think, i have a 84 2wd reg cab short bed and a 83 reg cab 4x4 frame, i plan on using a 85 302, c5, 1354 manual shift, gm tbi fuel injection, same as the howell fuel injection kits just cheaper, i have cage 5.5 early bronco coils, toyota leaf springs, i have a dana 30 with 4.10s and big 297 ujoint, 8.8 4.10s with disc brakes, i plan on boxing the frame and adding some more structual support to the frame, way to much flex in the frame for me, any other suggestions would be helpful, and yes i know the weakness and strengths of the d30, its what i have for rite now.
