LSX questions

[Dustmaker65]

Need to be educated on LS motors...lol

Bought a 6.0 that is totally disassembled. Everything looks to be in very nice condition. Was told it only had 66k miles on it, and came out of an '10 Express Van. The tranny came with it (6L80) and all of the wiring.

So what motor is this? LS2,3,4,5???

Is there anything special about this motor that I need to check into?

I do need a complete bolt kit for it. The guy had planned on replacing them, so he thru them away

Gaskets??? Any special head or intake gaskets needed?

Thanks! I am sure I will have a ton more questions putting this back together.
