I have a HEI distributor from a '83 Blazer on my 1958 283 block. Any recommendations for spark plugs, and what should I gap them at with the HEI? This is for my 69 El Camino w/ TH350 transmission.
When my friend Rick & I built the motor, he set the gap. I forgot what we went with. I just want to give the car a little tuneup now that there are a few thousand miles on the engine. The plugs have actually been in there for a few years now because I rebuilt the engine before anything else (wanted to make sure it would run and drive before investing $$ into body work). Thanks, John Nasta
