Anyone have a truck with the year 2020 introduced Ford 7.3L V8 ? https://media.ford.com/content/dam/...ies-super-duty/7.3_Engine_Fact_Sheet.pdfHave there been any magazine tests of trailer towing fuel economy against Stellantis and GM pickups? Has Ford issued a considerable number of TSB’s ? (Chuckle) Do you have to remove the entire pickup cab to replace a blown fuse? Ford has tweaked it some as a crate engine: https://www.topspeed.com/heres-what-fords-v-8-engine-lineup-currently-looks-like/sample quote The most significant changes come under the skin, with H-beam connecting rods, forged pistons, and a forged crankshaft. The cylinder heads are CNC polished, while the low-profile intake manifold houses a 92-millimeter throttle body from the Mustang GT500. Ford says the design is compact enough to fit in cars and trucks, so we could see this engine make an appearance in several models down the line. For now, though, it will go on sale as a crate engine, which should be available starting in the spring of 2023. Pricing is as yet unknown, but the base Godzilla crate engine costs $9,175, so expect Megazilla to cost considerably more, perhaps in the $15,000 region. end quote I am curious whether modern diesels ULSD price, DEF cost, and particulate matter filter re-gen headaches make gasoline trailer towing less per mile

This summer the local electric co-op was trimming/clearing their line along our western property line. I was talking to their forestry/procurement manager while we were looking at their chopper. It was BIG, could handle up to 18" stuff.
He said that they were all gas now after decades of diesel models. The gas simply do a better job now, are less expensive to buy, and have less maintenance and repair costs. Took them all by surprise, but they have had the gas ones for several years now and are not going back to the diesels. Surprised me too.
Master, again and still

I know that last couple of years when the price of diesel was crazy I did the math and my 5.7 Hemi Ram was cheaper to trailer with than my 6.7 Cummins diesel. It all depended on the wind direction, weight I was towing, and distance...
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

From what I read, even IF diesel fuel was the same price as gasoline or cheaper- the modern diesel engine is so expensive, complex- repair and maint heavy ( unreliable) that many see- despite the bad fuel mileage of gasoline- running gas engine trucks is cheaper and less liability than keeping the modern diesel engine running.

My company has a bunch of 550's with the V8. They seem to be a lot more reliable then the diesels they replaced. They seem to have good enough power. Terrible fuel economy though. 7-8 mpg. The guys have to fuel them every day. They have a GVR around 16k For comparison I drive a M2 Freightliner with a 6.7 Cummins and it gets around 10mpg. 26k GVR. Have you had any emissions issues with the Cummins?

The 7.3 "Godzilla" gas V8 from Ford was supposed to be the next big/great thing. Forged knife edged crankshaft, deep skirt block bullet proof from top to bottom, strong rods- pistons and heads that flowed a ton of air with a fantastic combustion chamber. The engine builders- even those not into Fords were all raving about this engine 4 years ago. The cam in block design guaranteed none of that DOHC complexity and nonsense. It's a shame this design has had to have a power reduction.

It's a shame this design has had to have a power reduction. They always reduce the power in the fleet vehicles rated over 1 ton. F350 has 400 something horsepower and an F750 with the same engine will have 275 or around there or maybe less. I am sure the reasoning it longevity at 100% load.

Some of it is emissions now- CARB used to have NTE emissions regulations for dyno certified stuff, but they moved to a moving average window calculation for the 2024 model year, and it applies to both gas and diesel. All of the big incomplete vehicles fall under that requirement.

Dodge did the same thing with the 6.4 hemi

"Have you had any emissions issues with the Cummins?"
Not really. The only problem I have had with it is a clogged egr tube. It threw a code and slightly de-rated. My truck is a 2010, (I got it new fall 2009) so no def, just regen. I run the truck very hard going back and forth over Donner Summit. It gets good and hot for mile after mile. About the only time it regens is when I run the pto for long amounts of time.
Do you ever stop there for "lunch"?

I can put another entire 6.4 hemi in my 3/4 ton for just the price of injectors in a modern diesel and we do turbos and other ginormous repair bills on diesels all the time also. With my simple formula for a 6.4 build they tow awesome and get great MPG for a big gas engine. They get heat working faster in the winter, start easier, less fuel filters, much cheaper oil changes, less fumes, less weight makes ball joints and other stuff last longer... I can't even come close to justifying the much greater expense of a diesel. I got no EGR to clog up or delete and no DEF to fart around with.

The hemi has better low lift flow but basically everything ferd did with this engine is exactly what dodge has been doing with the hemi.
