Estimated Power Increase...
well people have asked me this question before but i cant answer it. maybe arch or jess will have an answer...
well right now i have about 160 horses and 200 pounds of torque at the flywheel. heres my cam specs: duration of 195/201, valve lift with 1.5 rockers of .394/.409, an LSA of 109*, and an intake centerline of 111.5*. the cam i'm getting has a duration of 204/214, valve lift with 1.6 rockers of .448/.472, an LSA of 112*, and an intake centerline of 107*. i dont know much detail on the heads cuz i dont have a CC or a flowbench...but i think the ports are both around 85 cc.
so anyway, based on this information what will my cam, 1.6 roller rockers and port and polished heads put out when i'm done?

I've heard of bench-racing, but never bench-dynoing.
If you want a guesstimate anywhere NEAR accurate, grab a copy of Dyno2000 or Desktop Dyno, and play with that. Torque is usually off, but the horsepower specs are usually within 5 hp or so.
