for those of you with gt2-3 cam, does your engine run very smoth at idle?
im chasing a rough idle problem at least i think i have one. i can here the backlash in my blower at idle which tells me its alittle rough plus i can feel it sitting in the truck. I have tried numerous things to pin point a miss but know luck.

well in my opinion sbc's idle a little rough anyway. in my tbss i can feel the rough idle all the time, and have since i bought it. it actually shakes the vehicle.

Gone, but not forgotten!
If you are getting backlash in the vanes of your S/C, then you either have problems with:
Tensioner Pulley
Vacuum Leak
Injectors
You need to remedy this problem quickly, cause you DO NOT want those vane bearings wearing out prematurely...

Gt2-3 idles really smooth..if by backlash you mean a clacking of the S/C blades just bump up your idle...mine did that with my new cam and had to bump the idle to 850 to get it to stop..
