I am dealing with noise from the HEI distributor on an 1987 Chevy V30 service truck. I have ran as many grounds as I could find and cleaned and reconnected/replaced as necessary as well as added grounds up to and including additional grounds to the radio chassis. Thus far I cannot get the popping from the distributor to clear up. I have even put in RFI suppressing spark plug cables in.. I'm at a loss.
