Well for an example, run your engine to 9,000RPM for 5 days of racing and let me know how it holds up, probably would not get a pass or two outta it! Luke KNOWS what he did to his engine, he over revved it for the week, and got just what I would of expected him to get, a dropped intake valve, and I TOLD him what would happen if it was over revved! The engine has a somewhat agressive hyd. roller in it, and a 2.250, heavy steel intake valve, I told him 6900rpm was it, who knows what kinda RPM he was screaming it to, but enough that Brian announced one time, "listen to that thing, he's got it wound up like an 8 day clock"!
