I'll be straight up and say that I'm not a cammer expert. When these things cost over $40k, no one really sells enough of them to be an "old hat" at them.

From what I can tell, there are nicer, beefier parts out there now, made by 1 or 2 suppliers. Most of the issues I have seen have been timing chain issues.

As far as performance, in my mind, they are up there with Boss 9 stuff. The heads perform extraordinarily well, and when coupled with some displacement, it can make for some big hp without having to run high rpms or high compression. It's not uncommon to see 700-750 hp out of these engines without really trying hard.
