When I get back in a few months(yes, I'm getting deployed somewhere for about three months) I'm going to sink some money in my car.

I was wondering if someone could give me an estimate on horsepower I might get with this setup(sorry, not sure what the lift on the cam is going to be):

289
670CFM Holley 4bbl street advenger seires
pertronix eleitric points
45,000 volts coil
8.8mm wires
headers w/ 2½" pipes that end at the rear tires on the side of the car, not under
peformence air filter
looking for a good four bbl intake(not sure what type)
2:80 gears
c4 tranny 3-speed


I'll list more when I get it all put on.
