After digesting the results, David Butler comments, "The numbers look very good. We've seen 600 hp and 600 lb-ft of torque, sometimes slightly more from this combination with compression toward 11.5:1, which should operate suitably on 92- to 93-octane fuel with the aluminum heads. This wasn't a 'dyno' combo, however, which might typically include borderline compression, a huge camshaft, and a large carburetor. Instead, we took a conservative approach based on the vehicle's intended use."

Interesting choice in intake for the build. Guess i wouldn't consider the Victor for a mild combo like that.
