Who,s running 11.1 CR
What CR are you guys with 408ci running for N/A engines and if your running in the 11s are you running 94 octane or less with out any problems of detination. And another question has anyone built a 425 ci. and has anyone gone .060 over

Not solely, no. Dynamic compression takes into account other variables like your camshaft profile, air intake temperatures/pressures/altitude, volumetric efficiency and other things I can't recall off the top of my head. Google search "Dynamic Compression" or "Dynamic Compression Ratio" and you'll come up with a few good articles worth reading.
