What is up with this?

Why mess with success?

What will make a 4.8 better?

If you're standing still in the truck business, you're moving backwards. I imagine a redesigned V-8 would be more powerful and more efficient than the current 5.0. Probably work with the new 10 speed as well. It just makes sense to stagger engine redesigns, first a smaller ecoboost, now the 3.5 ecoboost, next a new V-8.

BlackBoost

New technology, and benefits from a lighter engine block. Think about the old giant engines, like the 7.something liters from way back when. Engines half that size now make more power than they used to.

Because the new EB puts out about the same horsepower with nearly a 100tq advantage.
More horsepower, torque, and fuel economy perhaps?

Making it .2 liters smaller won't help with the torque, unless they jack up the compression and use DI. Even then it won't help that much.

I doubt they'd go smaller unless they knew they could bring the numbers up in doing so. We'll see what they come up with.

There's already at least 2 other threads about the 4.8l going. Really need another one?

Brand

Some people can't be bothered to put forth effort to find what they want and expect other people to find it for them.

Even when there was activity in the other two threads within the past two days and would have been very easy to find

Imagine if someone told you in 1995 that the 2015 5.0 would have 385hp and 387tq and run on 87 octane? You'd think they were dreaming. That was 9psi numbers back then. With the ohc ford can't run displacement on demand like the competition so the only other option is make the engine smaller and try to improve hp with efficiency. I'm guessing the di version will have about 12.5 compression.

Dropping displacement from 5.0 to 4.8 and adding 2 points of compression will increase it from 387 to about 410 ftlb.
