IQ52, thanks! This helps give hope to my 400.

The timing of this is perfect.
Yea it is. It seems to be closer to a bragging point. The higher compression helps make that larger cam work better and it does add a good amount of HP, but the draw back of running the high (or very high) ratio can take you to high octane pump or better real quickly.
At approximately 3% more power per 1 point of compression, it can pay off in the right arena.
A lot depends on your wallet.
