That doesn't mean you will make any power up there. All the LS cars I've tuned (and you can look at other dyno graphs) show that the LS head and Intake manifold starts to drops off RAPIDLY after 6,500rpm. It doesn't matter even if you have great rods and pistons and a built bottom end. If the head is left untouched then the rev limit of 6,800 is the perfect shift point for best power. I've noticed a tad higher like 7,000 works as well.

That'll help considerably. Were you actually making power up that high though? Did you dyno it?
