Blower cam??
I am putting a p1sc on my '05 Z71. It has the L33 engine, with pacesetters and an aerochamber. Is there a cam that would work better for a forced indution setup like mine? I have been told that the cam doesn't really matter with a blower but I was just curious.
Thanks in advance!!!!

I cam will definately help!
Mine will be going in next weekend and I hope to get 40 rwhp with cam and tuning. There are gains to be had.
Not sure about which cam would work with your combo since you have a centrifical blower and I have a roots. Good luck.

a lot of guys are running the gt2-3 and have good gains with it.
Here is a link with specs:Lingenfelter

If I remember correctly, the L33s comp. ratio is 9.9:1. You might want to lower the compression ratio a little by putting some thicker head gaskets or/and some LM7 piston heads, to run more boost and prevent detonation. (just my .02¢)
How much boost are you thinking of running? Are you gonna use an intercooler?
Here is some info I found at Procharger:
Thought you might like to know this. 
A cam would definatly help and the Lingenfelter gt2-3 has shown very nice gains with the FI guys...but, just like j's01silverado said, most guys with the gt2-3 are running roots type superchargers, so I don't know if the cam will act different with a centrifical supercharger either.
Hopefully someone with more knowledge on this will chime in soon.

Here is some info I found at Procharger:
"For Intercooled ProCharger EFI/TPI applications with compression ratios less than 9.5:1, boost levels of 14-17 psi can be safely run with full timing on pump gas, and will produce horsepower gains of 75-100% (depending upon the boost level and the motor specifications). For 9.5:1 EFI/TPI applications running without an intercooler, boost levels above 5 psi will require the use of ignition/timing retard on pump gas, and will produce horsepower gains of 35-45%. Boost levels above 12 psi should generally be avoided even with racing fuel on a 9.5:1 motor. Of course, lower compression motors will be able to run more boost, and higher compression motors should run less boost, everything else being equal. All Intercooled ProCharger systems for street applications are designed to allow the use of pump gas with full timing and will not affect daily drivability.

just as an fyi, to my knowledge the GT-7 was the cam designed specifically for the radix, not the GT2-3. That in no way, takes away from the amount of success seen using the GT2-3 with the Radix.

Yeah I thought about going ahead and cam my 5.3L, but I think its going to be just a waste of money since I saw how easy it is to switch to a 6.0L. Now I want a cammed 6.0L, it never ends.... hahaaa
