Who will swap for the new 7.3 V8!

[Norm Peterson]

If you're referring to the profile of the cam, it's still fixed. You can adjust the cam phase angle with respect to the crankshaft on the fly, but the intake to exhaust phasing is set. The beauty of separate cams for intake and exhaust is the ability to modify things like valve overlap while the engine is operating.

It also makes one wonder why we're still messing with cams anyway when a solenoid can act directly on the valve.

Actually, it is possible to incorporate VVT into a "single-cam" OHV engine. But you have to think a bit outside the usual camshaft design box. Think "cam in cam".

The new 7.3 is a VVT engine. I may have missed where that was already said in this discussion.

I am going to guess ford is using this mostly for intake valve control. Hence the diesel like torque numbers at low rpm.

Mustang 360.......Mustangs and Fast Fords have the full write up.
The 7.3 was and is designed with all out performance in mind.
The 7.3 is said to be a bit "Shorter" than the Coyote and as we know, a bunch narrower.

So the nay sayers can cling to the Ultra low 87 octane tune numbers.

As for me......bye bye coyote.

You never had a coyote. You have no first hand experience with the car or the engine. You're not buying this engine, you're not doing a swap, and it will be cheaper to put an s550 into the 9s, and more fun, than to stick this truck engine into anything after a Fox body.

This thing is a big giant low revving HD truck motor. Cheaper to throw a blower on your Coyote and alot more fun. The day you get done, you'll be looking for a way out / back.

You do realize that I sell engines? Mostly used? Yes, I've owned a coyote.

The 7.3 is by far the better of the two.
In 1 ton truck form, the 7.3 almost betters the coyote and it does so with a very conservative
87 octane tune that would just kill the 5.0

You should research the hp difference from 1/2 ton 6.2 vs 1 ton 6.2
Also research the 5.0 1/2 ton vs GT
This will get you on track about hp differences from a GT - 1/2 ton - 1 ton perspective.

 

[Erik427]

You can study the hp difference while using the Raptor too.
6.2 1/2 ton vs Raptor vs 1 ton.
3.5 TT 1/2 ton vs 3.5 TT Raptor and then throw in the Ford GT's 3.5 TT

So yea, the 7.3 is the better of the two and by far.

 

[Erik427]

The 7.3 has a single exhaust.
Wonder what a dual exhaust will do for it?

You may sell engines, but you know nothing about them. The 7.3 is better in the heavy duty truck than the coyote, that's it. As a performance car engine, it's an anchor.

Working at a backwoods WV U-Pull-It isn't exactly the same as being a performance engine specialist.

In truck tune.....but only in truck tune.
Ditch the ultra conservative 87 octane tune.

Still a far better design than the mod motor derived coyote.

For use in a Mustang, neither engine design is as good as it could (should?) have been. But as far as production fitments are concerned, we're past the days of throwing more and more displacement at it.

Here's a litmus test for this whole 7.3 into Mustang thing . . . Vorshlag has been swapping LS engines into all sorts of non-Chevvies for pretty much the same reasons you keep bringing up for the 7.3. If they ever jump ship and start working with some derivative of this 7.3, that'll be when dropping it into the S550 (or even the S197) might start looking like a reasonable swap. Not just do-able simply because it can be done.

Nobody is arguing that the 7.3 is not better for truck use. The disconnect is insisting that what's good for truck duty is also going to be good for Mustang duty. Though I suppose if all you want is a low-revving understeering pig (truckish enough?) whose best claim to fame would be its ability to turn expensive tires into smoke on demand . . . welcome to 1967.

How about instead of me looking up information about vehicles I have no interest in, you post up those truck HP numbers for me.

If the 430HP in the 7.3 is the ultra conservative tune, what is the even lower 350 hp tune? The super ultra mega conservative lol

That is where the entire thread spun out of control. The OP wanted the engine as is in truck tune in a Mustang which would be an insanely expensive swap to do just because.

I don't think anyone is arguing the engine couldn't make big power with a new tune/cam and all your usual tinkering.

 

[tokuzumi]

Could we see lower displacement pushrod V8s make it to the F150 and Mustang? Maybe. But Ford is really going balls deep into the ecoboost, so I don't see them putting a lot of R&D into a new NA V8 that will see low production numbers for a few purists. Especially since the coyote and voodoo engines are serving their purposes quite well. This 7.3 will sell in huge numbers because of fleet super duty truck sales.

Now you're arguing with yourself.

Dyno cert vs chassis cert. Class 4+ chassis-cab requires dyno certification of engines for emissions/GHG.
