4.8L with LS2 cam
I'm thinking about getting a LS2 cam and springs and take a day off at work and throw it in my truck. I was reading that the LS2 cam is basically the same as the 01 LS6 cam. You can find LS2 cams all day for about 50 bucks if you look... All you need is a Gen IV front cover and timing chain sproket. Anyway, what kind of power increase would I likely see. My other mods so far are, custom Flowmaster exhaust, K&N FIPK, Electric fans, Corvette Servo. I am saving the tune for after I get the cam in. This would be going in a 2003 Silverado RCSB 4.8L
Cam specs are...
Lift............In.525 ---- Ex. 525
Dur@.050...In. 204 ---- Ex. 211
CL.............In. 118 ---- Ex. 114
LSA.......................116

I may be talking out of my rear here, but I don't believe that an LS2 cam will work in a Gen III engine. An LS1/LS6 based cam can go into a LS2 but not the other way around without modification.
I assume that is what the Gen 4 front cover and timing chain sprocket would be used for.

The LS2 cam will work in the Gen III engines. Its the same size physically, it just lacks the reluctor wheel for the cam sensor on the back. The Gen IV's run the cam sensor in the front cover and it reads the cam procket.
Their was a guy on ls1tech that put a LS2 cam in a LS1 and ran fine but it kept throwing the cam sensor code. So to run this cam properly, you would need a Gen IV front cover because it comes with a sensor, and a ls2 timing chain set.
