LQ9 Performance Cam

I'm putting an LQ9 motor in my Sierra. I plan to run naturally aspirated because supercharger kits cost MORE than a brand new LQ9 motor. Does anyone have any suggestions for cam specs?

Fuel economy really isn't an issue

thanks!

The new LS2 cam should be a interesting starting point for 6.0L cams. Good hp and torque. Supposed to be numbers close to the 2001 LS6 cam. The "old man" cams that have been posted would also work nice, but require a little more attention to the valvetrain.

You'll need a high torq cam which means medium durations.
Check the MTI SS1 220/220, .581/.581 115 lsa.
Comp 216/220 would be good too.
Or Comp 212/218
