Oct 06, 2003 · GENERALLY SPEAKING, .060 over on a SB400 is stretching it beyond the safe limit for a street engine. Yes, .030 is the preferred max, but if it has already been bored .030, and a .040 bore will clean it up, you will usually be OK on most SB400s. Just for the very reasons above, my preference is to bore a SB400 only .020 if that will clean it up.
