Why is this topic in the performance section?

Guys I wouldn’t fret too much about the limitations of the F150 in cases like towing long distances. For one thing having ridden with other drivers while towing medium to heavy loads with various tow vehicles I can unequivocally say that at least half the problem is the “nut behind the wheel” and I mean that very seriously. Commercial vehicles like F450 and F550 have tuning maps that are blunted for the very simple reason that drivers abuse the hell out of their vehicles as a rule and not the exception. Secondly transportation and vehicles meant to be mobile will be completely rethought in a very few short years. There will be trailers of all kinds becoming more streamlined and many will be equipped with their own battery storage system which can and will serve as a battery extender for the tow vehicle. Many campers for example with be covered by a solar array and will actually serve as both a remote energy reserve and probably also be able to supplement your home’s needs after a power outage much like the F150 Lightning can. Elon Musk has spoken about this but rarely I hear anyone mention it. The so called “grid” of the future will be very different and will be comprised of power generators, storage facilities owned by communities and eventually millions of private home and vehicular storage points. Eventually society will be sucking up solar energy in various ways on a scale no one is even talking about yet, except Musk.

It’s not just a cost issue with the pistons. It’s the location of the top ring. On a normally aspirated modern engine the top ring is located much closer to the top of the piston. This is done to reduce unburned fuel and thereby clean up emissions. This ring placement leaves less material strength above the ring land. They can crack or burn far more easily. A typical piston designed to withstand a power adder has a lower ring placement leaving a much stronger and cooler running piston dome.

With a crank mounted 1:1 oil pump you are over pumping oil sometimes by a lot. As rpm’s go up cavitation can be a problem.

I don’t know how true it is but I heard Robert Yates had some input on the LS cylinder heads.

What’s the deal with port injection and “bowl” pistons. Seems like those would be more in line with a DI system. It will be interesting to see the breakdown here.

I just watched a video that says the 6.8 has a forged crankshaft and the same 4.22” bore as the 7.3 with a shorter 3.68” stroke.

You utterly and completely missed my point.

Check it out man. Ford is building V8’s in 2022, that’s a blessing in itself. These engines are probably some of the last of their kind. I look at engines like someone might look at a lathe or a milling machine. An engine can survive and be revived for a hundred years. If an Achilles heel is built into something it’s a detriment for a looong time. This is especially true if the competition is not building in the same hurdle. The two main oil galley system on the 351 Cleveland just killed that engine’s reputation not because it didn’t work. It’s that there was no headroom built in on an engine that was capable of much more than it was delivered with in the cars it came in. I just want Ford to be the best. That’s all.

I don’t know what bowl shaped pistons are for but I’m not crazy about a cast crankshaft. Im sure it will be fine as an entry level engine but the outgoing 6.2 has a forged steel crank. Guys that bolt on blowers might find the limits on that crank.

Also 7Mary3 what makes you think the cylinder walls in a 7.3 aren’t thick?

You will see a 6.8 Godzilla

A couple things here. The block is made out of iron on the 6.8. I’m almost certain of that. Second, as I came to discover from a talk on TFL it is an actual fact that an electrified vehicle like a hybrid will be legal in post ICE California. For how long that’s another matter. See the thing is lots of F250’s and 350’s are sold for consumer use which would give Ford a huge incentive to offer an “electrified” Super Duty.

I bet one crisp dollar that the 6.8 will be coupled to a Powerboost system similar to the 3.5 Powerboost. I know I know you heard me pining for that combination in the Raptor R. No such luck. I can’t think of a more dynamite combination of a brawny V8 given the opportunity to get diesel like fuel mileage while at the same time becoming the ultimate work truck/over lander/ race car or toy hauler. What if? What if Ford gives us an F250/350 with all that capability? Not only that an electrified Super Duty will be able to skirt that California ban on ICE vehicle sales.

I don’t remember where I read it but on another forum someone claims to have been told by “someone in the know” that the 6.8 is a larger version of the 6.2 rather than a smaller version of the 7.3. That doesn’t make any sense at all but nothing makes any sense to me anymore nor am I ever surprised.
