Not everyone hauls 20k lbs every day. A more powerful gasser is the ticket. The operating cost are much higher for a diesel. Back when diesel was cheaper than gas you may have made the numbers work. Now diesel is $.60-.80 higher than gas. Never mind DEF, particulate filters, and all the other nonsense on diesels now.

I also had a 6.0. It was used to pull duel tandam 20k trailers every day. It got less than 10 mpgs pulling a load. I'm going to question your loaded mpg numbers.

The pushrod engine came after OHC engines. So,OHC engines are out of date:)

I guess that depends on your criteria. GM has had 637 CI V8, and 702 CI V12 gas truck engines. Albeit in medium duty trucks.

This will probably be an amazing engine-swap down the road once they hit the junk yards in crashed trucks. Iron block, port injection, 7.3 liters plus an aftermarket twin turbo kit. Massive power and torque!

Looks to be a beast, I would say 500 horse 575 torque are modest estimates. Big displacement, likely long stroke, cast iron block with cross-bolted mains and a gear-driven timing setup with VVT. I dig it.

It almost looks like a carbon copy of the SBC too, unless Ford went back into the history books and looked up the 5.0/5.8L OHV V8s they made years ago.

And I thought Ford was a big proponent of overhead cam power too?

I don't find it bears any resemblance to the SBC? It doesn't have siamesed ports, if anything I think it looks more like the FR9:

Considering the inspiration for the Modular was the 427SOHC, I don't think it would be surprising if their efforts for another pushrod mill resemble the Windsor.

And yes, Ford has put a lot of effort into OHC V8's since the 1990's, but they have brought with them their own suite of issues.

Diesels were literally regulated out of the market! Started with Low Sulfur fuel, idiots didn't want to see Big Rigs rolling coal, and yes diesel should be cheaper than gas.

They are for the most part. However trying to make a tall deck big bore DOHC V8 isn't very do-able in any modern application as far as packaging goes.

I like push rod engines and this looks like a winner! It looks like the spark plugs are easy to change. banana

slobber the FR9 is so sexy. They have one at the NASCAR Hall of Fame and I was fogging the glass looking at it.
