More specs on the 272:
It's gone back to a DOHC (4v/cylinder) setup and all four cams are adjustable (which is why the EGR system is no longer needed).
Has variable intake and swirl flaps at certain partial load situations to disturb airflow and provide a better mixture of air and fuel.
No longer has utilize oil level/quality sensors, no FSS and 13000 mi/service intervals.
Dipsticks are back!!!
2 cams are chain driven, the other two are gear driven.

Just some little snippets of info. We'll see how this one holds up.
