What is the correct plug gap for the 502 ram jet, I know it is pre 2003 but don't really know if it is the mefi3 or 4. One place shows .035 and another shows .045. I had already went with the .035 when I saw the .045. If it is .045 what will happen if I leave them at .035. It seems to be runing fine and a miss it had at idle is now gone. What I pulled out is about .045 but I figured they were worn. I used the spec AC Delco 4 rapid fire.
