I can't get a straight answer out of anyone I know as to what I shoulg gap my plugs to. It is a 75 3/4 ton Suburban with a new 350 crate motor and HEI. I keep hearing .035 and .060. I have no idea which one to use. I know I could split the diffrence but I am heading on a 2000 mile road trip and want everything to spec. Please help.
