Without writing a thesis about all this just consider this.
the coyote has a 6,000psi direct injection pump, sprayed in cylinder liner and a plastic oil pan. You have to be a fool to think these will hold up when the miles start piling on. The tundra 5.7L has a normal 60psi port injection, proper cast iron liners and a metal oil pan. Spray deposited liners are unheard of in the truck world, this tech comes from race engines and motorcycles, when it wears out the engine is effectively junk.
Did you notice that ford never offered the coyote as the base engine in the super duty? There's a reason for that, it can not and does not meet the durability requirements that the 2v 5.4L did. Same can be said for the ecoboost 3.5L, it makes the power but it will not live long at higher load cycles.
all this doesn't matter as people trade the trucks in every 4yrs chasing the latest tech and shiniest grill. If you want a long lasting ford truck you had better buy a super duty.
I hear you man. Seems like a solid theory on your end. The way I see it, it is just different tech. Simpler is not necessarily always better. I’ve seen 5.0 motors be abused... borderline sadistically... and the ****er’s still go strong. Same for their trannies. I’m not saying that there aren’t any issues tho. Just like with the 5.0s, the 5.7s have experienced their own flaws; random catastrophic failures, cam tower leaks, slipping trans, etc.
5.0 motor is leagues ahead of the old 4.6 and 5.4, I am actually surprised that you think otherwise. Eco boost is not even in the conversation, as I am not a huge fan of it.
I am not seeing all these issues with the 5.0 that you are talking about. I’ll keep my eyes peeled tho.
