Block Prep for a new GM LS2 block
So my question is if you were to buy a new LS2 Block from GM is there any machine work that would need to be done to it? I could see honing based on what ring set is used but beyond that is it ready to run?
I am trying to decide on building a 383 with my exsisting block or go 402. My engine has 43xxx miles but has 5 cylinders with broken top rings. Still need to pull the pistons and see if a ring land is broke. From what I can see the cylinders still look good(no gouges or scratches) and has a nice cross hatch in the bores.
Thanks
Chris

I was told a gm block needs just about full machining. It was about $500 bucks to have it all prepped. In the end I just had TSP build me a short block and had it delivered to my doorstep. The savings was about $500 over building the short block myself versus buying one. If you already have a block to work with, you can save a lot of money not having to deal with the shipping costs. I would have had to go out and find a block to get the extra cubic inches I was looking for.
