Are you going to substantiate this claim? I don't see how a rod with its symmetrical shape would ever impart a twisting motion in tension or compression.

I never heard of twisting myself, not to say it cannot happen, but never once heard that...

Cool. I'd like to see pics of those twisted rods.

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 thats different from boat engines but as others have said.... tune up.. Clearences when built etc etc will blow one up quickly.
