I was wondering, and can't seem to find a good source, how much an LS2 block can be safely bored out. The first LS1's weren't very much and the later blocks were slightly more but exactly how much? Does anyone have these numbers yet? I was just wondering if the LS2 design promoted more serviceability/rebuildability with more bore/honing options.

There is a thread further down discussing this topic.

Thanks, I had looked at that post before and I either forgot or was still wondering the actual exact specs. Is it gonna be .010 or 0.020. Or will dry sleeves get us 4.200 bores while leaving 1/5th of an inch between cylinders. I should just post in the other thread for this.
