I didn't go a quiet as big as Billy suggested but I like my cam. Comp reverse split - 222/218, .566/.562, 115 LSA. With Allen's street tune and 95*F ambient temps, the truck was making close to 600hp at the crank at 10psi. It has just a hint of lope at idle. Just enough to make it interesting but not threatening.
My engine is stock on the bottom. I don't see any tranny mods in your sig; that'd be my next suggestion. Mine lasted one week at 10psi after the cam and TC install.
Billy...what are the specs on that turbo cam?
Edit...now I see the vette servo but think you might a little more than that.
