At What Boost Level Is Aftermarket Iginiton Required?

I realize this will probably be different on every car, but I am just trying to get an idea. Does anyone here get by with their stock ignition without any problems and if so, how much boost and power are you making?

I will be running between 7-9 psi on a mild 302 (GT-40 Aluminum heads, Cobra Intake, Stock Cam w/ 1.7 RR) is the basic combo, Cartech Street kit with a T-64.

It is probably 75% complete...but I did not invest in an aftermarket ignition...will this likely be a problem?

Thanks in advance.

Dan

i think the stock ignition will be fine, the only concern i have is you will have to lower the gap on your plugs and im not sure how low the gap before your stock ignition wont fire the plugs my gap is at .30 but i have MSD
