Also, keep in mind that a lot of those OEM muscle car HP ratings were exaggerated to help sell cars, and his engine might not have actually made that much power originally, regardless of what the specs said. Many of the late 60's muscle cars were rated at those #'s when they were dynoed with headers, but didn't come close to that when the exhaust manifolds were installed back on them and rolled off the showroom floor. So for him to try and compare what he has now seen on the dyno probably isn't that far away from what it originally made back in the day. I think you'll surprise him for sure.
