Amen, Mr. Cab and I apologize (especially to my buddy Andy) for going O/T.

I have no doubt whatsoever the motor does everything that Andy sadi it does, the gearhead and Tech-junkie that I am can't help but wonder where and when in the powerband (specifically) the power comes from versus a more standard type build...that's all

I will say that I'm satisfied that above 5000 or so valvetrain stability really comes into play, to the point where personally I wouldn't build a 650-ish HP motor without something more stable than the OEM style cast-in pedestals....especially with a solid roller type spring!! I'd love to install an industrial type multi axis motion transducer into one of those cast aluminum pedestals (argualbly not even as strong as the oem cast iron) just to see how much shakin' is going on . I can't afford the Jesel stuff for a street build, but again the One-piece billet block (Race W2 style) pedestals really seem to help.
