say you had a 425hp engine with 10:1 cr, Then dropped the compression ratio down to 8:1. Then the engine would lose 6.5% power or 27.6hp in this case.

Shortening up the mechanical advance slot and running a lot of initial ignition timing helps low compression engines gain more throttle response. What does your timing curve look like?
