LS7 sleeves aren't thin. Bored them +.030 for N/A to patch up a block.
One issue have with them, 90% of pistons for them are 4.125", the block itself is 4.126", once you go to hone the block its only going to get bigger. I'd like if the piston companies would make pistons 4.127" or 4.130" more so then 4.125".
If you're reusing the stock pistons, i'd go with 4.125 +5.
