I'm trying to figure out what rear end gears to get here and I'd like some help if possible by someone with a dyno program. I'm trying to figure out where my peak torque and HP are.

My engine is a 350 chevrolet . Its .030" over . I have a .030" head gasket, zero decked, 1/8" domed pistons,

72CC chamber 200 cc intake port world product sportsman II heads which gives me about 10.2:1 compression. 2.02 inatke valves and 1.6 exhaust

The cam specs are .494" lift intake and exhaust . 232 degrees intake duration 234 exhaust on 108 degree centers. Roller tip steel rockers.

Air Gap RPM Intake. port matched

800 CFM edelbrock EPS carburetor

1 1/2 primary headers with 3 inch mufflers

HEI with MSD module

Need anything else? Any help would be appreciated

first thing... .030 quench? thats too close...even for professional engine builders...lingenfeller says .045...most others say that never closer than .035.. have you checked valve clearence with the domed pistons?

DD2000 says max hp @6000 is 382....max torque @4500 is 392

whoa

i need to do a better job of proofreading. That should be .060" gasket with zero deck. Thanks for the numbers. No problem on the valve clearance.
