A dual overhead cam 4 valve 426 with the latest head tech applied to it,would make for a good HD engine. That would bypass alot of the issues this generation of cam in block engine has.

Let's do it!

Put our work hats back on and buy out Peugeot-Fiat.

That said the whole thing with the twin turbsky's needs to be upgraded to a bigger single turbo in the trucks.

Unless you're on the strip, why would you want a single turbo? More turbo lag and no advantage at the RPMs you're going to spend the vast vast majority of your time driving in, I don't get why you'd consider it an upgrade.

We're to the point HP/TQ is mostly marketing. Who really cares about peak numbers they can tell you about in the commercial vs actual drivability and time under the fatty part of the curve.

They already have everything in the parts bin to build a 426/7L ,and i think thats the way they should of went.

They aren't even focus grouping large gas engines as best I can tell, but I can tell you 100% they are focus grouping the Hurricane with current and potential HD customers.

Yeah, and I told them they ain't makin' it, and why.

So they'll ignore me because that's not how it is in Europe! (Peugeot & Fiat)! I lived this dream at work for 6 years for a now failing division.

Say, how're those Fiat 0500 sales going, btw? I don't seem to see any anymore. I just.can't understand why?

I just cant see using a wrung-to-within-an-inch-of-it’s-life 6cyl in a 1500 much less an HD. It just seems counterintuitive.
I am on Rick’s thought process, an improved V8. Hell, twin turbo the 5.7 with better valvetrain/internals. Gimme 500hp I dont have to aftermarket enhance!
Who am I kidding…500hp just leads to 600hp…

my point was the practicality for the added hp and torq. why put in a 2nd turbo when they could have just upgraded to a bigger turbo to begin with. the turbo could give you the torq for pulling to help the little 6 cyl

Nobody in upper management listens to their customers anymore,they're to busy worrying about their bonus's to pay attention to the guys actually buying the product they're shoving down our throats.In the HD world the simpler the better in my opinion,so that means dump the turbo's and give us a few more cubic inches with a long rod,to keep cylinder wall and piston stress to a mininium and throw some good overhead cam heads on it,and you'll have an engine that'll live for a couple hundred thousand miles while being worked

Primarily due to turbo lag. One big turbo has more mass, mass decreases acceleration, and decreased turbo acceleration means lengthier turbo lag as boost builds. Smaller turbos moving the same air spin up faster resulting in the same amount of boost but faster. This makes the power delivery more linear, meaning it's more predictable and you get the power "on tap" vs "ringing up the engine room".

What makes you think it's "wrung-to-within-an-inch-of-it's-life"? 500 HP for a turbo inline 6 is, well, no where near an inch of it's life. If it's built properly with forged internals, proper cooling and oiling, 500 HP is nothing.

Look at the 2JZ-GTE. People are getting 1500+ HP out of those 3.0 I6 turbo engines.

And who's to say the truck version won't be different? They could opt for an iron block, different turbo's, internals, cam profile and tuning to put out 450-475 HP and 450-475 ft/lbs, moving the torque to come on early like we'd want in a truck, while maintaining reliability.

Turbos changed from large mass optimized for max.load only some time ago.

25 years ago, a waste gated small turbo provided a step load solution. It was a crude attempt to reduce turbo boost lag. It solved the lag, but didn't provide optimal boost curves, being a single step change.

Now days, the complicated variable vane full size turbo is used. These provide constantly variable boost controlled by electronic closed loop actuator. It fixes the issue at high cost and low durability, like most gizmos these days.

The differance between Toyota and FCA/Stellentis ,is Toyota used to build engines that would last,FCA/Stellentis not so much,lol. If the engineers had free range to build what they wanted they could probably build a decent inline turbo 6,but by the time the bean counters get done cutting corners,i'm not so sure how much i'd trust Stellentis to build a decently long lifed high output inline turbo 6,that'll live a long life while being worked hard. Maybe i'm wrong,only time will tell,but FCA/Stellentis doesn't have a great rep at building products to live much past the warrenty period

I've forgotten all the Fiat jokes from the 70's, after they went crawling back to Italy after their disastrous foray into as N.A. market.
They made GM's Roger Smithmobiles look like gems by comparison.

Younger members have no idea how bad they are.

Except all turbo wheels have rpm speed limits, known as critical speed. They come apart above this rpm.

So - the little wheels can get your boost quickly, but can't provide the full amount at high engine powers.

Hence the waste gated and variable vane technologies.

I'm sorry but I'd never buy that contraption. Ford would love to sell me a drop dead simple big block 7.3, putting out 475 lb/ft of torque.

But would it have MDS?

GOTTA have it for .00001+ mpg, yes?
I use the word never cautiously because that’s a long time. I’ll never buy another Ram with MDS.

Maybe you should be looking at the engine you are touting. It's plagued with issues. Cam/Lifter failures, harness failures, valve failures. It's a Ford product. It's a p.o.s. on 4 wheels.
