Comp Cams not responding

I've had good personal experiences with Lunati and Erson with catalog cams. FT solid and HR respectively. Our shop uses a lot of Bullet cams that are custom, as in we order all the specs and they send us cams made that way, regardless if they feel it's "ideal" or not.

I've heard nothing but good things about Mike Jones, and if you want a custom cam, that'd likely be the way to go. That said, cam action is all mathematics, and the only real variables are how far you want to risk things with regards to acceleration rates, spring rates, valve train inertia and so forth.
