LS2s are aluminumIf it was me, I’d go with an aluminum 5.3. 100lbs less weight makes for more jumpy truck action.

80hp seems a little far fetched if we are simply comparing GenIII truck engines, the 5.3 (LM7) to the 6.0 (LQ4) both of which are the 2 most common engines to find used and In fact they're only 15hp apart.Just from a quick internet search, the 6.0 has about 80hp over the 5.3. For $300-$400 that's a pretty decent upgrade. I'd go 6.0 if you can swing it.
Do it. Displacement helps. Sure they aren't far apart stock, but with later mods the gap widens due to that increase in displacement. Your application is one where keeping it wound up isn't a bad thing so a Gen III setup is ideal. Watching videos of Nate's Papa Smurf on the sand with the 4.8 at full boil proved that one for me.Leaning towards the 6.0 due to torque curves. Have s line on an lq4 harness eco, accessories with 127k on it. It has 40 psi of oil pressure at idle. If I can grab it next week I will.
I must have looked up the wrong numbers for the 6.0.In fact they're only 15hp apart.
