Ok Camshaft experts here you go!!

Of those two, the thumper is closer to the 380, and I like the 107 lsa better than comps 110 (comp, EVERYTHING is 110).
I am leary of a cam that is ground to produce a ratty idle, and a sound, more than power however.
Have you looked at Lunati? I like a lot of their grinds. Mostly the voodoo's.
