Just my 2 cents butt most of the time when a Rod fails.... something else has happened first (spun bearing) oiling issue "something" its not to often they just break , not saying they can't or won't break but rarely.... I was IHRA Record Holder in 84 and 85 in A-Gas 468 bbc with tin-dipped chevy rods 8600 rpms never a problem. I know that different from boat engines but as others have said tune up.. Clearences when built etc etc will blow one up quickly.
