[stang85]

I have a question about what plugs to use. I have an E-cam advanced at 4deg, underdrive pulleys, torker 2 intake, edelbrock heads w/2.02 valves, around 9.5:1 compression ratio, 1.6 roller rockers, shorty headers, 650 double pumper( brand new today) was running a 600 vacuum secondary, h-pipe, msd 6al, t5 trans, and 3.73 gears.

Anyones help is appreciated.
