I am running 11:1 and the duration on my cam is between 240 and 250 @ 0.050" I was asked that I not share the specs on this cam so that is as close as I can tell you to the actual specs. I can tell you that this thing is a beast. It is a Dart block 363 so not to far off from what you are building. Gordon estimated with my parts combination 525 - 530 hp @ 6500 rpm and somewhere around 475 on torque. Runs great around town and has more power than you could ever use and still gets 17 mpg, what more could you want.
