I thought the same thing initially but I don't think that is much more than a performer RPM hieght wise. If the runners are sized good it should be a nice runner. I wonder if they can get a cam to support that air flow now. A quick look on the net says max HP RPM was only 3600 RPM with around 150 horses. Interesting for sure.
