what would be the suggested Spark Plug Gap for a lightly modified 318?
Has an upgraded Cam (previous owner installed, brand and specs unknown) Holly Carb, HEI distributor, using Royal Purple HPS 10w40, and currently running E3.46 spark plugs.
.045 seems right imo.
I know chevy uses .045-.050, chevy style ignition would make sense to stay in that spec. @RustyRatRod
Ignorant? Hey let's not let our brand loyalty lead us to insulting others here, we arent ignorant...we know you like that big cam sound you get when your champions insulator falls out and starts to miss. Not fooling no one.lol
