I have a 327 bored .060 over with flat-top trw cast pistons and 64cc heads. Lots of static compresion. Ratio is about 9.6-10:1 and I did the math (the 9.6-10 range is for any minor miscalculation). SO, the compression is up there for pump fuel, which is what I use. I had a hard time with detonation/pre-ignition. I had to richen the a/f ratio and go with colder spark plugs. Good Luck....
