2015 5.0 v8
Here was my 5.0 V8 going through an extensive engine replacement due to a warped cylinder bore causing an engine knock at cold idle. It also caused metal shavings in the oil due to marring of the cylinder walls which also let oil past the piston rings and began burning oil. Basically a catastrophic failure. The block, timing chain, cam followers, cam phasers and every gasket were replaced at just 25,000 miles. My lifetime fuel economy was around 12 mpg, I never saw above 14 mpg even after the engine work. This happened in March of this year, and the tech that did the work said that mine was the 14th 5.0 engine replacement he had done yet this year for the same issue.
If you try to tell me that the 5.0 is less issue-prone I'll call BS. So I figured that because neither engine is more prone to issues than the other, I picked the Ecoboost for my next truck. It's quieter, better on fuel, faster, better for towing and no more issue-prone than the V8.

No engine is bullet proof, it's a numbers and probability game.

Yeah that sucks. Compared to the ecoboost engine/turbo replacements? Everyone has the potential to get burned. The bore issue on the 5.0s occur early in their lives. Always under warranty. The ecoboosts carbon issues will bite after warranty is gone and turbos have failed all over the board.

You got some numbers to back that up?

Definitely won't regret the 5.0. Test driving the eco, the 5.0 has that power under your foot at all times without lag like the ecoboost. I also don't see the longevity of the ecoboost quite yet. Until the ecoboost is a 15 year old motor proven 250000 miles regularly, I don't necessarily trust that twin set up. The 302 has been around since 1967 and there is a reason for it. And thats why I went with the 5.0. I don't quite understand why everyone is going away from the motor. Heck, the salesman looked like I had punched him in the throat when I told him I wasn't walking out of the place in an ecoboost.

You cannot compare the 302 to the 5.0. They are two entirely different motors. The 5.0 doesn't have a very long track record either. It is shorter than the ecoboost. That being said Ford did a good job putting as much "race" tech as they could in to it while keeping it affordable. If I kept my vehicles for a long time then I would have went with the 5.0 for piece of mind as well. Less moving parts, lower cylinder temps and pressures can never be a bad thing.

I went 5.0 because I am a little suspect of a motor that small putting out numbers of a much bigger motor. Its all me and my mind set, there is no merit to that any where its just in my mindset. now next truck I just might go with a smaller motor.......... hell who am I kidding ill get a 5.0 or a f250 diesel before that happens

I agree the NA 5.0 is under less pressure to produce the numbers it does as opposed to either eco-boost.
I am still not that impressed with my 5.0's towing ability but I am being a bit unrealistic. More importantly, I don't tow that often so I don't mind having to tone it down a bit.

But the fact that your 5.0 is putting out more power than the big blocks from days gone by doesn't bother you? Aren't they the same thing?
