And reliable. Absolutely has to be reliable or it will devastate the reputation like the 6.0L PSD did. Everyone raved about the "new" 6.0L engine, until a few years later, and then all Hades broke loose.
UPDATE: I had originally heard that the cam phaser was in the back of the block, but it is indeed up front; Good! makes serviceability easier.

Here's a video of the Windsor engine plant with some 7.3 engines and assemblies. Very impressive to say the least. Although my next truck will be a diesel, I'm very impressed with what I'm seeing with this new engine and would purchase one of these over a 6.2.

Agreed. I'd like to see a deep, broad torque curve. Something that has 80% or more of peak across 2000rpm spread would be wonderful!

I would expect 400/425 hp and 500/550 tq. With the 10 speed ratio this thing should have been designed to offer an extremely high % of it's torque @ or below 2,000 rpm as it has so many gears to work with to stay in it's ideal low rpm efficiency range. My only concern would be long term carbon buildup / pinging due to low rpm operation. However, if they nailed the stoichiometric ratio, which is what they are claiming led them to 7.3 L size, it should be a very clean and efficient burning engine. The low rpm design should yield good ( for a 7.3 ) fuel economy. This engine should never break a sweat with 10 speeds at it's disposal!

I would agree, 2.7. But I don't think carbon buildup is going to be an issue; I cannot recall a fuel injected engine in mass production within the last 30 years that is had issues with that when running right. The old 5.4 L was an animal at low RPMs, and never seem to have issues with that.

Yep, port injection will certainly keep the intake valves clean. I'm not sure Ford ever had a problem with it, though… I spent a lot of time in the F150 forums and have owned two EcoBoost models. There are raging debates on whether or not catch cans are worthwhile, but I cannot recall a situation where somebody ever had a problem with carbon buildup.

I noticed the new GM 6.6 gas DI has an elaborate baffle and filter system for crankcase ventilation, factory catch can more or less.
Wondering why the delay on releasing power numbers on the 7.3? Marketing? EPA testing? Surely Ford knows the numbers.

Yep, a buyer like me. I'm ready to either pick up something used (6.2 or 6.7) pick up a 2019 New or wait for the new 7.3 which kinda sounds like what I want. Hopefully the numbers come out before initial orders go in beginning of August.

At this stage of the development process it hasn't been certified by the EPA, which means the final calibration is still being worked out. It can't be rated for horsepower until a final calibration is complete. Remember there is a tremendous amount of regulatory hurdles that must be overcome before an engine can be put into a production vehicle. Just designing the engine is only part of it.
