6.7 Cummins vs 6.6 Duramax
As someone who knows next to nothing about Diesel engines, I am trying to figure out the strengths and weaknesses of these to. Any opinions would be appreciated.

Our 2009 Duramax has been flawless. Number 8 glowplug is the only engine issue we've had. Had to replace upper and lower control arms, tie rods and shocks. 167000 miles and going strong, hopefully another 10 years with him.
