Need some help here, please

I'd run the Street Avenger 870 carb. Cam' a little small but it will make mad torque. Intake is fine. If you want to put a real cam in it, the intake could be the single plane MP. ETs with a stick depend on the driver, but you should have the mile-per-hour to run in the 11s. Also depends on the tire size. Most strokers like yours will make peak horsepower around 54-5600, so usually a milder gear is better. I think 3.91s with a 28" tall tire would be ok but it's been a while since I played with the calculators to see what you'd be trapping at rpm-wise.
