HP Specs on 350 w/ Holley I have a 86 Chevy 350SB. I have the following parts for it, including headwork:
-750 Holley Carb
-Holley 14PSI Electric Fuel Pump
-Comp Cam Coils 273Lbs@1.250
-Edelbrock "Torquer II" Intake Manifold
-MSD wires and entire electric upgrades all MSD
-Hedman Longtube Headers
-All New Gaskets
-3.73 Rear Gears
-5Spd Manual Tranny *(Rebuilt)
-Upgraded Pulley Kit
-3 Inch Exhaust w/ H-Pipe to Dual Exhaust exiting rear of car
Thats all I can think of right now. I know there are a few more parts. But I am not going to mess with the pistons or crank for right now, maybe in the near future I will bore it out and upgrade crank. But, Can you guys help give an educated guess on what this set up will be pushing??

Hard to say.....You're leaving out lots of info like combustion chamber size (what's the head casting #'s?), compression ratio and whether the cam is stock or not. If they're run of the mill smog heads & dished pistons with a stockish cam I'd say you're probably somewhere around 280-300hp at the flywheel, give or take.

The cam is far from stock, so is everything else. My friends say it should be in the 400-450 range, but Im looking for other opinions. And yeah, I've posted 3 threads on important questions concerning my situation with the Z28. I am in the middle of major work and that is what this place is for. Can some body direct me to an oldschool forum?
