Hopefully someone can help, I have a 93 with a 99 gt40 motor, f-303 cam, ran great until I pulled the motor for a front and rear main seal change, moved msd box from fender well to the tunnel inside the car, running a 84 distributor because the car was stolen, got back a shell, put a harness out of a 89 and carburated it. The msd box tested good but I have no spark now any help would be greatly appreciated.
