A while ago, before the V12 was born, I asked one of the techs at our Agco dealer how the Cat engines in the Challengers (they're all tracked tractors here) had performed compared to the Sisu's in the Masseys. He said they had a lot more trouble with the Cat's, but the caveat was that the Cat engines were worked hard in general.
