Living with the duramax vs the 6.0L?

I like the ability to work on the LB7 and LBZ quite a bit more though. All three were really good to me. I’m not sure where you are getting the constant hate on the duramax from, they are very good engines. If You want to see how good some of the power strokes are, start looking at the 6.0 and 6.4’s lol. The Cummins is a really good engine in all of its variants thru the years. As a rule of thumb the earlier the engine the less power it will have but the ability to work on it will be easier.

Well it seems that the LBZ and the L5P are the ones to have. The others had a lot of fuel system problems, some that would destroy the fuel system. Sure there were work arounds, but as always people want their stuff to "just work" without having to spend a lot of money doing a conversion to fix a factory flaw. Given how much we pay for these trucks, who can blame them.

Because of this, all the others besides those two engines are basically problems waiting to happen, unless someone has already retrofitted them. That's most likely where the hate is coming from. The one right before the LBZ seems pretty nice, as long as you don't mind biting off $1,200 or $1,500 to fix the flaw right after you buy it. The power levels and reliability seems to be the same after that's done. This is just from my research. After what I've read, I would only buy trucks that had one of those two engines.
