My 6.0 swap! Srj is the man!

[$750 L98]

Lq9/4 block
317 heads
XER281HR Cam 113+3 232/234 595/598
Comp 921 springs and titanium retainers
Comp R lifters
LS6 intake
Shorty headers
True duals
Stage II 4l60E
2800 stall
Tuned by A.R.D

And that pretty much covers it as far as I remember. Just a cammed 6.0 with supporting top end/exhaust mods.

XER cam is not the T2 cam, but that makes little difference. Even with the shorty headers choking the engine, and running through a stalled auto, you should have done much better than ~290rwhp. The stock CR of a LQ4 is 9.41:1, low, but not crazy low.

Just wanted to tell you that my buddy dyno'd over 100rwhp more than you did with the same heads, a smaller cam, and a stock LS1 intake manifold...
