Fords new 7.3 liter engine for their HD trucks. Doesn’t look like an OHC engine to me...

Forgot to add that I just got this from automotive news. Far cry from their OHC offerings. When I bought my ‘11 FX4 you could get the 6.2 OHC engine as an option.
Hope this isn’t old news.

Nothing wrong with pushrod engines. Like any engineering solutions, they have their advantages and disadvantages. OHC engines, although seen as modern, have a lot of disadvantages that keeps the pushrod engines employed to this day.

There's something to be said for the simplicity and reliability of pushrod mills. GM's success with the LSx family, and its compact nature, as well as Mopar's HEMI have proven it isn't obsolete yet. I couldn't imagine trying to turn a wrench on a comparable displacement OHC mill in my Jeep crzy

The new 7.3 is indeed a pushrod engine. Cheap, simple, and plenty efficient for the rpm range they will be operating.

Yep, yep, and yep. Low end torque, lighter (to increase available payload for one), simple reliability and proven design durability. They'll probably put a 5w40 in it and never look back.

I take it the power ratings haven't been released for the 7.3L gas or the Gen 3 6.7L diesel ?

I'm curious to see how this engine does. I'll probably be in the truck market in a few years.

Oil cap in the video I watched showed 5w-30.

Negative but the new 6.7 is rumored to be in the 500hp and 1000+ft-lb range.

Now that RAM and GM have released their power and towing numbers, Ford will undoubtedly claim more.

This should be a HORSE of an engine. Fords V10 was only a 6.8L mill if I recall. The Biggest gas truck engine to date was the GM 8.1L I just don't see the need for such a large gas engine that will undoubtedly get horrible economy. Why not just buy a diesel if you require this much towing capability?

My notoriously hated 05 PSD with the 6.0 averaged 15-16-mpg loaded to the gills hauling a 3 horse trailer with living quarters, 3 fat mares, tons of excess junk and other items when we moved from WV to Florida, over 975 miles.
