Alright guys I've got a 1965 ranchero that a swaped a 302 into out of a 1986 bronco. I have a brand new distributor for a 1969 torino in it. New plugs, wires, coil, points set at 20 thou. Freshly rebuilt 4 barrel holly carb. New electric fuel pump. I mean you name it I've done it but all it wants to do is barley idle and with any rev it just backfires through the carb and shuts down. I have exhausted my time and money to no avail. I need some new ideas on what to try guys.
