How much do you think a used LS3 block is worth with 17,000 miles on it? A friend is selling his to put at 427 in his Vette. I might pick up myself, still need to do some research. I have of course LS2 and what makes a LS3 what it is the larger pistons and more flow heads right? He already got rid of the heads that came on the car so the only thing he has is the block and internals with that.

What do you think?

My son-in-law is in the process of purchasing a used LS3 (10,000-miles) for $5,600. You about covered it on the difference between the LS2 and 3.

Was that a complete motor?
