Getting the most out of a low comp 440

I'm knocking my head against a brick wall trying to design a build/compression ratio without quench around the 87 octane. I wouldn't mind having to play with the ignition timing according to fuel and usage.
I hear ya brother..I've done the same thing more than once..recent thread on 440 stock rebuilds had some ideas...on this site started by ABODYBOMBER...
