check it out,
I installed
RPM II intake, 75mm throttlebody
cam
30lbs injectors
port 302 heads
rollers 1.6

it runs strong but sometimes its starts to smoke grey but not 24/7 just some times so its not a constant thing, I know I got big injectors but im planning to stroke my engine real soon, I really dont know whats up with the engine, maybe a o2 sensor or even the ecc
HELP!!!! :worship:
