Does anyone know what the correct gap on the spark plugs are for a 1989 s10 blazer 4.3 non vortec? Im doing a tune up on it and cant find the gap distance. I tried to just measure one of the other plugs but the first 3 i tried were all abou 2 tenths off from each other so i dont want to trust any of them. If anyone knows please tell me.
