If you are going to gap the plugs @ .060, you will need a higher output ignition than the Pertronix. Even with a MSD6A I have found .045-.050 works fine. A wider gap without multi-spark can actually result in the spark getting "blown out" before igniting the fuel, it also puts a tremendous strain on the whole secondary ignition system(wires, plugs, cap, rotor, coil) due to the very high voltage needed.


I agree with the headers, intake/carb route, but will also suggest a high output multi-spark ignition with the dist. The MSD dizzy is a fine piece, but will gain little over good stock unit if not combined with their MSD box.(not counting adjustment, durability,looks, elec. of MSD dizzy) What I'm saying is performance will only improve if you take advantage of MSD dizzy's features and benefits.
