I've bot an 01' Z06 cam in my 4.8 and did not have to change anything and like the outcome of the new cam. Bout the same on the low end but on the top end you can really feel the difference, with other bolt-ons like headers, intake, tune, rtc you will get more out of it.

I used a 02+ cam. It does have a smaller base circle. I measured it and it was .050 smaller, but that's only .025 diff to the lifter, which is in it range to compensate for. Its running well but I'm having some random miss firing problems right now, but I think they are spark plug related. Going to through some new TR6's in it tomorrow and see if that fixes it.
