bore 5.3 to 5.7
was looking into boring the cast iron 5.3 to a 5.7 bore but was concerned about 2 things. one, boring out this far does it make the sleeves too weak? two, is there a hardening surface that gets lost boring out that far?

It works but it must be done by someone who has done many of them before. You need to see where the cylinders are more thin and bore accordingly. If done properly you should have no problems.
