I know for a fact that the 300+ hp n/a DOHC ka's are real because I have talked with the builder of them. The ones for the Baja trucks. Rebello builds them. They "redline" at 8500rpms but see 11.5k rpms when the trucks are in the air some times. Don't waste your time trying to build something like that, you'll never get there. They have nearly unlimited funds, and more importantly (something severely lacking here), knowledge.
