Engine builder questions

I do think my dyno simulator program is a little torque happy but I try to keep things on the conservative when I input them. The Horsepower & Torque curves are more important than the numbers. I was surprise how low and much the peak power was for a fairly mild 273 I think the secret is the roller valvetrain gets the most out of the head flow without going crazy with duration to keep bottom end, that's how I like designing an engine extending the powerband far as possible without sacrificing too much bottom end.
