Problem with SPF 1207
Have 200 miles on the Superformance and cannot get rid of the stumble and dead spot at 4300 rpm. Have 351\392 FMS motor, 750 vacum Holley. Dyno guys dialed in the carb and says the problem is in the ignition. Wants to change to MSD dist, coil, and box.
Figured I could tackle it one item at a time and see what it is. Bought a MSD 6AL with coil. Removed the Duraspark box and trying to figure out how to wire in the MSD using the cars harness. Can this be done, or do I have to wire it just like MSD shows in their manual? Some of you SPF gyuys must have done this before.
