Yeah, you see this is where this gets a little interesting.

My approach to this is if you have a 400 HP 9.8:1 347 that makes ~400 hp @ somewhere around 5800-6200 rpm. The motor I describe would have nearly identical power and torque up to your RPM peak...the Difference is that this motor would rev and continue to make power for another 1000 rpm.

I agree whole heartedly with your assessment of "most peoples" driving capability, and tractabilty. But if you put a 6000 RPM rev limiter on my motor it would feel very much the same as far as how it puts power to the ground....it's just this motor, by comparison, (to borrow from Spinal Tap) "goes to 11" , for guys like me that Rode a Yamaha V-max (Remember the Cycle World V-max vs Cobra article from 1985?) for years.

As for my mild 427 W, I control the tractability very easily because I simply shift to a higher gear. My motors torque curve feels more like a 455 Buick Stage 1 (shove in the back) in terms of driving. As I said the guys that drove the real deal 427's said mine feels "as close as it gets" to ones they drove on the street. They also said the 428's Shelby slipped into the later cars, were way slower than the Medium riser S/C 's
