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

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.

Man, I read the first post in this thread this morning for the first time and yelled a word I haven't said in years! LOL. Then I when I saw the mph... YUP!
