My RPM's be turning to get the full effect of a high rise manifold? I was thinking from 5500-6500??? I have an AB impeller and i cant turn it more than 5900. I think i need a lower cut like a B.

X2, if you have the HP at that speed to back it up, should be good to go, I would think. If you do, I would go down, not up.

What's your MPH at 5900 rpm with the AB cut?

And what's your cam profile?

What's your head set up?
