I need a little help. Today I put a Accel super coil on my HEI. At the same time I put in a new set of AC Delco plugs, R44T. I removed a set NKG's. I had read somewhere on this board that when putting a high output coil on the HEI, you should increase the spark plug gap to .060. Thus I did this. Now I was not expecting a dramatic increase in performance, but I sure did not expect to lose any either. Well I did, now it seems a little sluggish. Did I gap it to far? By the way the cap and rotor are brand new, and it already had 8mm Accel wires on it with only a few thousand miles on them. Any suggestions?
