FM11 & GMPP LS6???? I am wondering what power to expect? I'll make a list of my mods below to better help with the guessing.
346 c.i., GMPP LS6 heads 60.7 cc chambers, FM11, 12 bolt with 4:10's 6 speed, ASP underdrive pulley, LS6 intake, ported throttle body, Grott 1 7/8 headers, no cats, borla catback open.
This cam in this same engine with stock 241 heads, stock pulley, and t.b., with 3:42's made 390 r.w.h.p.

My car did pretty well with that cam through my AS Stage II 5.3's. I also only have 64cc chambers and am running a 6 liter gasket, so I'm down on compression a little. Numbers in sig.
