Most of the guys I race with are running custom cams...including myself. In the world of Trophy Stock, where we're limited to shorty headers and unported heads, the top dogs are in the elevens with a class record of 11.60@115 at 3200#. The T/S crowd will probably go even faster/quicker this year. To turn those numbers at that weight, you're looking at about 325rwhp and 350ft-lbs on the chassis dyno. As far as piston to valve goes, it all depends on what you do with the heads. We're limited to .500" lift with the cam but most folks are milling the heads pretty radically to pump the compression up. Most of them have the compression above 10.5:1, probably even some above 13:1.
