BB, I got one of them there HEI systems in my old 76 Vette. Running a .050 Gap on the plugs,but only after I put one of the high output coils from MSD or Mallory(can't remember which)in there. Darn HEI does not funtion very well at low RPM's though. If I putzs around at low rev's for any lenght of time,it fouls my plugs right up. Give me an old dual point distriutor and Mallory HO coil anyday. Shoulda bought a little bit older Vette,say maybe a 63?
