How much HP from SBM ProComps? Well... 670HP!

You should probably tell all the Pro Stock guys how worthless their dyno's are. And their spintrons. And the flow benches they use.

A dyno and a torque wrench are the same thing. You can make them lie. Why bash the tool? I could tell a guy + or - 3 MPH of what his car should run with my dyno numbers. ET is hook.

I didn't say dynos are worthless, I said it irritates me when they are used as a "sales tool" this very thread is a good example, engine builder brags in a open forum that he made the most power to date with procomp heads...but once installed in a dedicated race car, it ran 122 MPH... that my freind, sure as hell aint close to no 670 horsepower.
