I'm Awesome
I'm going to go aftermarket cam, I'm going to call up comp or lunati when i'm ready to see what else i'll need, probably an adjustable valvetrain. Hopefully I won't have to replace much else, depending on the cam.
ZZ502?
I dug around in my 454 vortec thread databank and found a Lunati cam recommendation. I didn't note who said it, so I can't give credit, but I'll look it up. (EDIT: Since the FSC site upgrade the forum thread numbers and post numbers are all different, and their search feature is not picking it up. They just can't stop messing with a good thing, can they.)
Somebody... said:Lunati’s Voodoo series of camshafts deliver more area under the curve than any other series of camshafts. This means more throttle response, quicker acceleration, more vacuum and better efficiency. These factors, combined with maximum horsepower and torque, make Voodoo camshafts the perfect choice for a wide range of high performance applications.Hydraulic Roller Cam. Very strong increase in low RPM torque and power. Works well with OEM style injection, great inboard/outboard marine cam for economy and sking.

Hopefully you're getting heavier springs. Stockers are reported to be 85lbs.
I've also got a note from someone saying that if you go more than .500 lift of the cam you'll need to have the valve guides machined down to get more room as stock is .520.
