As I recall, it's basically a small block Chevy w/ 2 cylinders cut off. Therefore it benefits from lots of R&D history. There are lots of high-performance parts.
It would not share a block with the 3800 series (which is a damned good motor), or the 60-degree line (2.8, 3.1, 3.4, 2800, 3100, 3400 and now the 3500). However, even if it does, these motors are now good for 200,000+ miles as well (don't remind GM of the early 60-degree stuff).

Are your talking about the new 4.2l in-line six that they are using in the Trailblazers and Envoy's. If so then I haven't seen any actual engine problems with them. Those two vehicles are having a lot of fan clutch failures though. This may seem rather trivial until you consider that they use an electronic fan clutch assembly like the Mercedes and it runs about $500 - $600 to replace.

I think it's actually a 4.3. It's also been used it boats quite a bit.
Problems with the EGR valve sticking from carbon on autos, otherwise good engine.
For a six, I prefer a straight 6, more torque and naturally smooth.
