Gen1dak will become famous soon enough

I hear ya. On the 440, I'd run 9:1 if running '67 closed chamber heads, otherwise more like 8.5:1 with the open chamber style. I get the feeling gas is gonna continue to suck, maybe even slide some in quality. Anyway, keeping the CR very conservative means more ignition advance and sooner, and that means more usable power "under the curve" and no knocking when lugging a load. And it's a lot easier to roll back the advance a little as opposed to adjusting CR later. Focus on cams that maximize midrange power. Anyway, just my 2 cents. Good luck. It'll be a rare bird.
