Cams choice, Low CR vs VE%
Well, for conversation's sake, the 400 I am building will have under 8:1 with a camshaft up in the 240s @.050" LOL Dynamic will be under 7:1. And you know what? I couldn't care less. It's going to run on any available octane, run cool, run reliably and sound nasty. In other words, it's going to be FUN.
