MOTOR LOSES POWER AT 8K all fresh WHY??

wow,im suprised you didnt fold over a bunch of valves at 10,000rpms if the cam timing changed!:S

New update, Went to the track same problem by the 3rd pass.

Ran a leak down and it did great so def. no bent valves. I've seen these things run real outa whack with the centerline and still not bend valves but I am truly surprised it din't bend any especially with that kinda motor speed.

As soon as I pulled the valve cover I found the problem, bound up exhaust cam bearing. I replaced all and everything seems good now. Try this again on wednesday!
