As I understand it, the trick is to design the cam so that it doesn't abuse the valve springs. Valve springs on a typical big cam that is used on a road course need to be replaced at least every season, or more often if you blow a couple of shifts. The cam profiles on this cam are more gradual. And the slightly lower lift of this cam is to prevent the valves from colliding with the pistons if you over-rev, which is easy to do on the track with so much going on. There's probably a lot more to it than that, I'll let the experts chime in if they have anything to add.

Here's the thing- The dyno results show that I didn't have to sacrifice much HP at all to achieve this improved longevity. This is an impressive cam.

I don't have any vids yet, but it sounds mean. Not extremely lumpy, but nicely cammed. I wore out the stock pads after just two track weekends, so it's in getting track pads and stainless brake lines now, but I may get a chance to video the idle in a couple of weeks before my next track outing at Buttonwillow
Looks like this is the type of cam I'm looking for! Durability, good power, not too radical and nice idle (I'll take your word for it till I hear a video clip, lol!)

Thanks for the info! I'm a newb at cams so I'm starting to do my research before it's time to drop the hammer on one!
