...but so to the point. Dropping from 10:1 to 9:1 compression looses less than 2% according to the old H.O. graph (also on Wallace website) -- and that's if you're running the proper fuel for 10:1.
For an engine putting out 300 rear wheel horsepower that would be less than a 6 horsepower loss. If timing has to be reduced from 36° to 28° to allow the engine to live, you might drop 5% or more (15+ horsepower).
