Spark plug gap
I have a quick question on spark plug gap. I'm running a 350SB with a mild cam, HEI ign and ACDelco R45TSPlugs. Can anyone help with the proper gap? Even the parts store is not sure if it's .035 or.045. I even contacted ACDelco and they told me to ask the parts store on the application? Any help would be greatly appreciated!! Thanks....
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
