Grand Am Cup Cam & L92 Has anyone ran it? I like the wide seperation on it. I think the low lift would be nice and easy on valve springs with a .570 lift. Anyone have any experience with it, or idle/driving videos of it?
How well would it work with the L92 heads?
TIA!

My current cam is a 244/250 -.596/.596 - 112lsa. It'd be easier to swap it now for something better though before it gets in the vette.

But, Dynotech Engineering put it on the rollers after an Exedy twin disk install. According to Exedy that was a big no-no and the clutch began vibrating shortly after. Should have put down more??
Here's the graph:
big split in duration could be an interesting study..I would think it would be a little light on lift but like you said easy on the valve springs. I would go with more lift to grab the extra potential out of the heads but in any case would be a very interesting combo. If you go that route please post u dyno info. Nice find.

I am bit concerned with tuning the 106 LSA but otherwise should be fairly straightforward. Should know next weekend.
