I'm surprised some of you guys are getting away with such high static compression ratios (11-to-1 and up). From what I've read, FE's with high SCR's tend to detonate easily because of the fact these motors need to use high domed pistons, versus 429's/460's which don't. Is it all in the choice of cams (read: plenty of duration and overlap) that lets your engines live at these high CR's?
