1998 - 2000 Fbody
202/210 int/exh @ 0.05" duration
0.496" / 0.496" int/exh lift
116 LSA
2001 - 2002 Fbody
197/207 int/exh @ 0.05" duration
0.467" / 0.479" int/exh lift
116 LSA
I'm not sure if they'd be different for Corvettes other than the Z06s or not. I'd assume not.
As going to a larger cam and not upgrading anything, I'm not sure. There are folks who put valve springs on stock cammed motors, so you might not be able to get away with doing no other mods.

You will need replacement valve springs rated to the lift of your replacement cam. Even putting an LS6 cam into an LS1 I would replace the springs. The stock ones just aren't rated for anymore than the stock cam. I would also suggest replacing the timing chain and going with hardened pushrods.
If you decide to replace the cam decide how much power you want to make and how much driveability you are willing to sacrifice.

The Corvette cams are slightly different from the Camaro, but essentially the same. Do a search herein for a full list.
The only exception is the 2000 Vette cam; it had .500 lift to offset the 4 cats installed on California cars. 01's went back to .478 lift.
Crane and Comp have a couple of tiny cams which they "say" can be used with stock springs - but why bother? You might get 8 hP, and if your stock springs are a bit worn, they might fail with even a tiny cam upgrade. You can install new LS6 springs for about a C-note, and the labor is tiny compared to the labor for the cam install.
So, go ahead and select a decent cam, install some LS6 or Comp beehive springs, get a tune, and see some serious gains for all your work.
