What Plugs?
I have a 70 GMC shortbed with a 67 396 that I just got a couple of months ago.
It has a GM HEI distributer and I want to replace the plugs and wires. What plugs should I put in it and what should I gap them at? Thanks, Dusty

Re: What Plugs?
With hei the plug gap should be .045. you can get the stock plugs for the motor just gap them farther. ac delco would be the better way to go.
