Yeah! I saw that, as you know. Any time you decide to make another run of those, I'm down for a 4 cylinder unit!!
The introduction of the hydraulic roller cam system has increased the lifespan and power/drivability of several other engine designs. The old LT1 small block Chevrolet and the later Vortec big blocks are two vivid examples. There was an immediate leap in available horsepower and drivability and overall durability increased exponentially at the same time. Electronic fuel management and ignition control would explain some of this, but the mechanical, (actual physical durability) can't be explained away by those other items. The later 3.0 industrial engines and the Mercruiser versions with EFI only make 130 to 140 HP, so the power gains aren't being produced there.
Whether coincidental or causal, there is reason enough to explore the potential of the roller cam system..
