I HAVE FOUND A 6.0 AND WAS WOUNDERING IF THE MODS THAT I HAVE DONE TO MY 4.8 WILL WORK ON THE 6.0? THE 6.0 IS MISSING THE INTAKE, WILL MY 4.8 WORK?

All of these engines are completely swappable. All their heads bolt onto eachother, all of their intakes bolt onto eachother, and all of the external engine bolt-on modifications are swappable too.

I may try and find a stock LS1 (aluminum) to stick in my GMC. About 30 more hp and 80 lbs lighter.

Couple of quick notes to that:
Yes the intakes are swappable, but the LS1 and LS6 intakes are much lower and the idler pulley on the truck will interfear with the T/B depending on your air intake setup. Also, the alternator bracket on the trucks will not line up on one bolt on the LS1/LS6 blocks. But those are relativly easy fixes. One more thing, the LS1/LS6 pcm's will have different connections. You will be beter off reprogramming your truck PCM.
