I absolutely agree with this statement . I maintain a fleet of 12 GM truck that’s all we buy because of the durability of the LS engines. While I would like to try a Ford super duty , the overhead cam system is simply not nearly as reliable and the engine in general is not nearly as reliable. I buy the 6.0 L gas engine, We are a fleet municipality , we don’t need maximum horsepower. We need enough horsepower but value long term reliability over acceleration . We have never lost a single GM LS engine . We do not get rid of them until they are rusted out bad, which is 16-19 yrs. My feet ranges from a 2019 with 2000 miles on it to a 2002 with 160k and 13,000 plus operating hours. Or 2015 and 2016 1 ton dump truck have about 30,000 miles on them and close to 4000 operating hours.... these trucks never shut off Driven hard and put away and before I got there the maintenance was spotty at best.I know the 1500 series had some problems with AFM , it can be deleted, or repaired like any other engine, the bottom end is very stout, and working on the GM LS is a pleasure compared to an OHC engine. . Workin on them and driving them every day I am not impressed with the truck itself , I hate the seating position and high hood and belt line . I love my Fords seating position, visibility and how it drives . I also couldn’t get the big 6.2 in anything but a top of line truck ... I wanted a mid level trim .....

Coffee out of nose! I guess those engines don't come to mind because they are Crown Vics and not F150's, though the 4.6 was available in the F150 too. The 5.4 is based off the 4.6, but Ford mucked it up with the spark plugs, otherwise they would be bullet proof as well.
I guess what they are saying about the non OHC engines is that the simplicity makes them easier to repair when the break. I mean, they have timing chains that stretch too, they are just much smaller and have only 3 parts. LOL

Let's be honest here. Ford didn't have anything to compete with the LS (N/A) that came out in 97 until 2011 with Coyote.

The LS7 is a badass motor but did have some (correctable) issues with the valves. The newer Z isn't based on the LS so has no bearing on this discussion. The LS series of motor isn't perfect but they're reliable, cheap, easy to maintain and can make big power. Not sure how anyone can hate on them?

I will easily grant you - as will many SAE members - that NYC (or Chicago) taxi cabs run probably the hardest environment for a car within the US and maybe the planet. But there are a number of car and engine combos that work that task.

OK if you want to go down that road - what about the number of taxi cabs out there with small block 350s, or the newer ones running Impalas with the GM 3.6L V6, or the ford fusions running the 2.0L 4 cylinder, shall I continue.

Most of the tear down investigations showed more issues with production defects than any engineering flaw. Remember more than the ones you read about are still running fine as from the factory. I mean it's not like any other major car maker has produced engines with some production defects.
