Yes I wouldnt go past 7600 and still stay wet sump

Thanks Tom. I would be running 93 octane and won't spin past 7,600 RPM. I would of course like to run the highest compression ration that is practical. With the forged pistons you install in the block, is the C/R 9.5:1? Also, it would be naturally aspirated only.
