No mention of the big displacement pushrod v8 that Ford's developing for trucks?

I think you're talking about the 7L? Pretty sure it's going to be a DOHC engine, supposed to be around the 500 hp mark.

The pictures I've seen are of a pushrod motor.

Can you post some pics? Kind of intrigued on the specs of this new motor. Mated to their 10 speed it should be a hit.

Got the DOHC from this article:

I own some modular Fords; they're nice and scream up top but, the lower end grunt of a pushrod motor just can't be beat. Although some of my modular Fords are faster than some of the pushrod motor cars that I've owned and own currently, they're just not as much fun in stop light to stop light situations which is what is more frequently experience when driving cars on the street.

It's interesting the old pushrod 5.0 had more grunt than the 4.6 even though the stroke was literally a half-inch shorter. I'd imagine the modulars are better suited to road course stuff vs. drag racing...?

Stroke has almost nothing to do with TQ, it is a lot more closely tied to displacement.

Thank you Dave, for restating that oft-forgotten fact.

Other thoughts: Ford's Modular engine represents a bad bet on the future of IC engines. They thought they'd be getting much smaller. By using a bore spacing of 100mm, they effectively limited bore size to 3.66 inches. As a result, the 5.4 and 5.8 Modular motors have a stroke of 4.165 inches, longer than a 454 chevy or 472 caddy. The 302 was never known as a torque engine, and the 4.6 is even smaller. It's a gutless wonder like the chevy 4.8 LS motor.

Also, the point about DOHC engines taking up space is valid. I remember the first time I saw a 5.4 ford crate engine...Doggone, that thing is huge!

The 6.2 Ford has a bore spacing of 4.53” (115mm) so they have room to grow. I wonder if the new 7L is based on this or is it a new engine?

One thing not mentioned is the price to produce.
IMO the hemi will probably get replaced with a V6 trurbo and the V8 will only be offered in the 2500 and up series.
The Fords are more expensive to produce.

*Was going to be replaced. Those silly 55mpg fleet average rules by 2025 are getting rolled back. It'll be made official in March, and for good reason. FCA didn't have a hope in he11 to meet them by selling Jeeps, Rams and muscle.
