Funny how you won't acknowledge your stock stroke builds. Shift points are often considered optimum 10% above peak power so maybe just maybe if you ever had your engine on a dyno you might see peak HP occuring at 6700-670=6030rpm. Also you are a porting guru and the op's heads are not ported from the sounds of it.
Still waiting for you to show me where I called you a bad name in that other thread.
Why don't you offer the OP your cam specs so he can run in the 9's too? J.Rob
