Why do you think that you have to spin that engine at that RPM to achieve what you are looking or? My low buck 360 will do that and all it has is an LD340 on it and never sees over 6000 for better longevity. And a 540/557 hydraulic flat tappet cam. Ran 11.70's with 60CC unported 1.88 or 2.02 heads (made no difference at the RPM range I was running) valve heads and a 485/495 cam, still not seeing over 6000.
Runs consistant 11.40's.
