Mr P sugestedthe rn12yc champion plug, what plug are you guys running in your iron headed 360 with 9.0-9.5:1 compression??

just curious I have always had great luck with champion plugs.

Or its equivalent.... he's running a 9 now and he's
having a issue with his plugs being dark.... but he
is also running 10* timing at idle 36 total, I suggested
a hotter plug and up his idle timing to 18 and
decrease his advance to keep his total timing the same
