Yes, my true, honest, no-fibbing horsepower numbers are between 450 and 475 at the flywheel. I get a little extra for the Ersons and the fact that it is nicely broken in and carefully tuned. But still, when people ask, I tell them it has 450HP because that's the truth. BTW, my valve sizes are 2.09 and 1.66. You know, if I just wanted to test out a bonus 50 to 75 horsepower I could bolt on shorty straight-outs and then put on some ear plugs.
