In my latest build, we went 3.375 (3 3/8") + .030. Not by choice, but necessity. It was the 5th block we went through and the only good one.
It was already out to 3 3/8" when I got it. Ronnie diligently sonic tested each bore at 12-16 points depending on the readings. According to his findings, there would still be enough meat left for one more overbore in the future. This 59L block may have been a unicorn, but it goes to prove the importance of sonic testing the block when going big.
