ok i have a o6 ss/sc i just installed gm stage 2 and a 2.79 pully and i put in ngk bkr7e pluges last night i took them out to gap them at .035 and they were an orange color i think am running way rich:eek: is there a way to control this that isn't expensive thanks for the help:confused:

um best bet is to get what plugs gm offered and test with those, our engines run rich from factory.

ok i'll try that thanks for the help
