657 HP with a 509 cam? Not by me!

Wouldn't matter anyway. Crank horsepower doesn't always translate into ET. I often race a firebird that makes 200 more HP at the wheels than I do and runs 1/2 second slower in the 1/4.

Hell yeah it would matter. Dyno numbers don't mean much without a timeslip. If this engine were in a 3200lb car running high 9's at 136mph, people would believe the big dyno number. That's all I was getting at. Until that happens, it's just a happy dyno number to sell engines.
