340 or 360 Thick walled block.

Any chance you have had them checked for thickness? I have bought a few blocks this year that by casting numbers and dates should be good blocks, when tested, are not. I really just don't have room for maybes. Lol
I understand but the blocks I have are rotoblasted, mag'd and sonic tested and the price would reflect that. The other thing is just how thick you are looking for, I have one that is at or over .200 everywhere but does need a repair, most of mine fall in the 180-190ish average range when all points are checked.
