But what do I know really im just going off a feeling from what I have experienced ... But that's all I got, my experience's, and you guys..... and a appreciate and value all of you!

Charlie, I would think that as long as you had a larger good flowing exhaust with low backpressure a larger cam with some overlap would be the way to go. Not the same situation, but my car has 9.3:1 compression with 26 degrees of overlap on the cam. It's just a solid flat tappet. Seems to run pretty good I think. I would think that a small cam and no overlap would cause it to be prone to detonation at 11:1, especially when the cylinder pressure rises even more under boost. No expert though, just my thoughts.
