Re: 8K RPM on the LT-5
From the dyno runs I have seen, ZR-1s have a power peak at about mid 6's. Not sure you need to shift at 8k and risk valvetrain issue. As Todd noted, you would need to go to a shorter runner length in order to push power peak up to 8k.

Re: 8K RPM on the LT-5
Area under the curve is more important than when exactly you hit peak power. Mine reaches peak power at about 6800rpm but it stays at peak till at least 7400rpm - as high as I've revved it on the dyno.
