Default difference between L92 engine and Ls3 engine?

I own a 2005 gto with the ls2 and have an opprotunity to get a deal on a L92 6.2L engine. What are the differences between the L92 truck engine and the Ls3 found in the 2008 corvette. From what I can find on the net the truck engine is still an all aluminum block with a 10:5:1 compression ratio. Anyone know the cam specs and compression ration of both engines as I have been unable to find the hardcore specs on the internet. Also what needs to be change to put it in my 2005 gto. Thanks

Intake manifold, accessories, and the LS3 has hollow valves.

I have LS3 heads, the ports and chambers had a rough sand cast finish.
