6.0 4x4 cam suggestions?
What I have: 04 GMC ecsb 4x4, 6.0l, 8" lift, 315/75r16's, 4.10 gears, manual 5 speed trans. cai, pp throttle body. Dual exhaust w/flowmaster 40's dumped before the axle, diablosport handheld tune.
Seat o' the pants. 1st gear, nice torque, revs fast, 2nd gear, struggles a little unless you wait to shift at 5 grand + from 1st. 3rd gear, pretty much the same. Third is a dog unless you keep it in the 4-5000 rpm range. 4th gear pretty much the same thing and 5th, forget it. Great for highway though. (this I know would be helped with gearing) but..
What I want: a few more ponies and some more torque to pull this thing without having to wind it out, although I don't mind, I do it all the time, but still...would be nice to flatten out the curve a bit.
I want a nice choppy sounding cam. I heard a few clips on youtube of some cammed trucks with moderate cams but 109 lsa. Sounded awesome, but are there vaccum issues with that tight an lsa?
Matt from TSP suggested a comp cams 212/218 lsx high lift cam with 115lsa. He said going with much more duration than that and it will suffer with torque loss down low. I am sure this would work, but I want something with a tighter lsa, 110-112. Anyone have any suggestions? I am in shopping mode now.

Guys have good luck with the tsp 220r also in 6.0L engines, it has good power offroading.
Here is some clips I found of the tsp 220r in 4x4 gm trucks.

oh btw your gonna want to get a custom tune from like blackbear, wheatley or one local and get rid of the handheld.
