I have a 64 c10 with a 292 and rochester b carb and hei that i can't identify as to manufacturer. had the carb rebuilt and valves adjusted by a reputable shop close by. ran great for a few days and even better with fresh plugs until today.when i accelerate there is a hesitation before it reacts. i have the plugs gapped at .037 because i have read you can increase gap slightly for hei.
my next question is about running dedicated 12 volt wire to hei. where does the wire run from? i can take truck back to shop as it is under warranty but wondered if i should regap plugs back to .035?
