It seems a lot of folks think even the classic 7.3:1 is too much, and will lower the CR down to 6.5:1 or around there. Then they also enrich the snot out of the carburetor and run very low advancing distributors like the 009 (no load advance) as if they're trying to keep the engine from blowing up or melting down.
