Just recently purchased an LS1 Block with a full rotating assembly. Had one of my buddies go out and check it out for me and pick it up since i had to work. So when i was looking at the block, i started looking at the main caps, and i looked at the number sequence and it goes 1,2,2,4,5. As soon as i saw that i realized i just got myself into a basket case most likely.

So heres the situation, do i spend the money and get a machine shop to hone the block, and check the crank, and look into align boring it, along with new cam bearings just to be safe? How much am i looking at worst case scenario? What else is required with going this route aside from all new connecting rod bolts, and main cap bolts?

This is my first experience with LSX/Gen III/IV engines so its def going to be a learning experience for me. Also going to have start looking into machine shops, would like to see it go to a sponsor or someone somewhat local to me, that has experience with these engines.

Any help is greatly appreciated
