It would be interesting to see how many VXes have had their engines actually replaced under Isuzu 10 yr/120k warranty. Personally I don't think the 3.5 (or the earlier 3.2) is a bad engine, or one prone to failure, I do think the point about failure in VXes should be examined a bit closer. The VX was rather unique to Isuzu in that it was built as a true rally inspired SUV - one factor that's very different between a typical VX owner and someone driving a Rodeo or Trooper is general driving habit. I think the VX owner tends to push the design a bit more due to what makes the VX so much fun - handling, performance, capability. That mixture could put additional strain on the engine and systems not found in the other models, contributing to engine failure. The general concensus has been that if it was going to fail, it would due so well before the 100k threshhold, with those few that fail at later odometer readings being questionable (abused or not maintained). A slightly flawed engine that's driven hard would show a higher failure rating than one that's not - is my thinking. Comments?

When you look at the history behind the Chevy 350 small block, I'm betting more in sports models failed than in trucks or vehicles that were more 'family' in nature. I about killed the motor in my 69 Nova just because of my driving habits when I was behind the wheel. It just came natural to push the motor a bit more than necessary - the "SS" badging on the car didn't help at all.
