262 @ .050, .630 gross lift solid roller,
451CI and E heads here. Makes max HP at 6300 rpm, has seen 6800 on chassis dyno and though it will go that high, the power falls off. I have the rev limiter at 7 grand and try to never hit it.

I'm not trying to be mean or mess up your thread, but honestly 6500 or 7 grand with a 230 degree camshaft is really not going to do anything...
