The reason I ask is that I'm considering a Powerquest 280 that has a Precision Marine 502 that has been modified to run naturally aspirated with 540hp at the crank. I believe this is equivalent to a HP525's power. The power was made with Dart high flow aluminum head, ported and polished intake manifold, high flow exhaust manifold, and a different cam. ECM tuning as well of course.
Am I basically getting an HP525? If so, WOW! |

I believe he said 30-40hp more per side, but you have to run 91 octane. He can also raise the rev limit to 5850 safely.
