Peak power with my ported intake and 2 inch headers was in the 6800 to 7000 range. Just depended on which parts we had on the engine. If you're still running the OOTB Super Victor then it might be nosing over a little sooner. I was running a 2000 cfm throttle body and I think you have a 1150 Dominator so that might be knocking a little off. I'd think you're in good shape if you are shifting at 6800 and then running out the back door at 7000. You'll just need to keep an eye on the valve lash and the plugs until you get some more laps on it.
