The most sense made in this thread. That's what I've been saying all these years but people can't get over the lb7 injector thing because there was a crazy long bulletin for them and all the forums have blown the whole thing way out of proportion.

I can say more 04.5+ trucks will make it to 200k with original injectors than lb7s could dream of!
6.0 have a lot of issues. They are a HEUI Injection. Meaning it takes oil and fuel to fire. Idle at 550psi oil at idle and 3800-4000 WOT. Spool valves get stuck that meters the oil
If you put all the updated oil plugs/standpipes/dummy plugs in, a nice set of injectors, delete the egr and if you go as far as studding it and CHANGE THE OIL, on time, it will last. I work on many since they were new. Deleted and coolant flushes with cat elc coolant will keep them running nice.
OK, now lets look at it this way. What are the odds of an LB7 with NEW style injectors with the updates in them learned from later injectors going 200K VS LLY's? The new style injectors with the hardened ball seats and so on are MUCH more reliable. Can they fail, yes. Have any failed, yes. But A DAM site less of them have failed VS the 1st generation LB7 injectors did. The other issue is so many people tried to cut corners and cheap out on replacements(Llike I did the 1st time around, and took 3 sets to learn my lesson), then have repeat failures over and over, and blame the LB7 injectors when in reality it was them cheaping out.
Don't know about the CUMMINgS, but yes, the CUMMINS does have injector issues as well. More on par with LLY's as far as the number of failures. And we won't even go to the powerstroke. The 6.0L and 6.4L have left a pretty tarnished image for FORD.
They blow HG's, turbos and egr coolers...
But when you make almost twice the rated hp on stock parts they all are gonna have weaknesses. Stock for stock the Duramax is king...
They come built to handle whatever GM feels comfortable throwing at em. At the rate they're going, it won't be long until a stock truck has 600HP under the hood.If only they came from factory with built motors

Technically he started this thread, even though his question has nothing to do with the original topic
The fact they are loud in the cab, ruin a bed floor, blow soot all over your truck, melt stuff in the bed, can't haul anything in the bed, can't pull a nice rig on a trailer behind said truck, etc..
