which plug do I need?
496 bbc, 13 to 1, 1050 dominator carb, 722 lift lunati solid roller, no NOS.
The car runs like crap first couple passes missing and spurting, but gets better every time trial and eventually straightens out by the third time trial and never misses a beat there after, the car is currently running the ngk v power # 9's
I'm thinking its too cold of a plug, what do ya"ll think?
Any recomendations would be greatly appreciated.
Its not my car but I do drive it and the wasted TT's are bugging the crap out of me.
Thx in advance, Charles
