I have a friend that used to be a Dodge Mechanic at the dealer I bought Geronimo at - he had a 1980 d-50 sport with the 2.6 that he shifted at rev limiter from new. One day I stopped at the dealer to pick up some parts, and he showed me what had happened while racing a 924 Porsche - the crank broke on #4 piston, spun around, and locked together so it still drove - he didn't know it was broke until he dropped the pan, although he knew something happened. He ended up totaling it by hitting a patch of oil on the road, spinning it around 180, slid along a section of guardrail, and went over an embankment backwards.
