Who will swap for the new 7.3 V8!

Actually, the auto industry is ruled by book keepers and finance people.

Actually I’ll give that one to you...

I have stated many times that I work in development. I helped develop 2 brand new industrial diesel engines, and have supported fuel system development of several diesel trucks/cars.

I don't think this engine swap will be so popular, unless Ford Performance or another engine builder makes a crate version. An LS swap is much easier, as there is so much support already out there.

I don't think it will be popular either, but it has its place.

As for an LS swap, sure it's cheap...but it doesn't have the capability to be bored out to 500ci and will never support the amount of HP that this 7.3 is going to support.

The swap most certainly won't be for the faint of heart, but that's the beauty of hotrodding.

The A10 is going to be more than adequate for maintaining peak HP. It does an amazing job with the coyote.

As for the extra torque vs slightly less HP, that's a great questions. It would undoubtedly be able to pull an amazing 60' compared to the coyote. 150 lbs is about .15 to .2 in the 1/4 mile. We also know that every .1 reduction in 60' is worth .2 in the 1/4 mile. My best guess is it would be damn close. The 7.3 is going to get out of the hole faster and the coyote will have a higher top end charge.

Possibly, I just think with everything we have seen the 7.3 AS IS will not be as good as the coyote in any performance venue.

Again I don't think anyone is saying the 7.3 doesn't have potential. It's the 7.3 AS CONSTRUCTED RIGHT NOW, IE an engine for an F-250/350/450 Motor home that people have a problem with.

That's the thing, we have a general idea of what the 7.3 will be as-is, and everything points to it being close. I too think it will come up short, but not by much.

I think people are making way too many assumptions based on the sole fact that the primary purpose of this engine is for heavy duty applications. They don't seem to fully grasp the concept that this is a brand new from scratch OHV engine design with a plethora of goodies that will likely make this a beast of an engine in any vehicle. This isn't a 460 big block with carb, flat tappet cam, iron heads and intake.

Couldn’t have said it better myself!

Better order another 55 gallon drum of lube, seems like every post in the last two pages is a frickin' novel - lol. Building up steam for 200 pages.

The head of gas engines at Ford has stated the iron block 7.3 is too heavy for the Mustang.

The head of gas engines at Ford has stated the 7.3 engine probably won't fit in the Mustang.

The head of gas engines at Ford has stated the 7.3 will not be very good for the Mustang.

The head if gas engines at Ford says the Coyote is the best choice for the Mustang.

Who knows.more about the 7.3, the head of gas engines at Ford or Fatguy, Mill, Erick?

"And if you're wondering if it'll fit in a Mustang, Beltramo told us it's actually shorter in height and narrower than a Coyote V-8, but quite a bit longer thanks to much increased bore centers. It's possible then, but good luck doing so without having to cut into the firewall. And even if you could wedge this motor into a Mustang, it wouldn't be very good, because of its heavy cast iron block and low-revving nature. Stick with the Coyote, kids."

How many times does that need to be said before it sinks in? These 'FACTS" bead off "7.3 truthers" like rain beads off a windshield treated with rain-x. It seems that you and Fatguy are using the same fact Repellent.

The 7.3 looks like a fine engine and will make you very happy in an F250.

If the aftermarket does decide to do things for this new big block, it will be interesting to see what can be done. Although, if Ford doesn't release any kind of performance parts for it, things are going to be expensive. If the aftermarket has to do R&D to design castings, it's gonna cost some serious money.

Of course, someone did swap a duramax diesel engine into a 5th gen camaro. Torque for days, son. There's also the Cummins diesel swap in a Charger.

Yet again, you fail to understand the difference between a "good fit" and "more capable".

You can hide behind Joe's quotes, but you have still yet to offer any evidence that the 7.3l wouldn't be quicker or have much...much more potential.

Looking at what this engine already comes with (hydraulic roller lifters, aluminum roller rockers, beehive springs, high flow heads etc.), this 7.3L is going to be a cam swap and tune away from monstrous horsepower. Just look at what happens to the 5.3L LS truck engine with a cam swap....

But it's a truck engine! It can't possibly be fit for a car!

But it's a truck engine! It's made for lower torque!

Everyone is more than aware of this. But I HIGHLY doubt the aftermarket will be interested in these efforts, at least not for a while. LS, LM, and Vortec swapping didn't happen over night.

 

[Big Boss]

I don't think anyone is arguing potential @millhouse I think we all know what a large displacement cubic inch engine is capable of. I agree with you, a new cam and aggressive tune and this thing could make tons of power.

What the majority are saying is:

@Fatguy wants the F-250 version of the 7.3 in his mustang as is. No new cam, no new tune, no performance potential unleashed. Just straight up truck motor in a mustang, which many are arguing (and you yourself agreed) the coyote in THAT application would still haev the edge.

It's going to cost a boat load of moneys

for that reason alone this swap, keeping the 7.3 AS IS CURRENTLY CONFIGURED and putting it into a Mustang VS going with a 5.0 makes 0 sense

 

[Maggneto]

Yet again, you fail to understand that the head of gas engines at Ford knows a hell of a lot more about the 7.3 and 5.0 than you, Fatguy, and Erick combined.

Joe knows that the 7.3 is a truck engine and will not be a better choice than the 5.0 in the Mustang.

But don't take Joe's advice, order the 7.3 and get to.work sparky.

We are all looking forward to watching YouTube videos of the 7.3 Mustang F250 losing at the dragstrip.

Whoever said swapping in a LS engine obviously never did one. I mean if your getting a junkyard LS yeah cheapish. They also come with the factory piston slap. Rebuild it or not. Up to the redneck doing the swap. But most serious guys will drop in the LS3 crate. $6500. Yay. Crate 5.0 $7500. Now for the LS you'll need harness, ECU, harness, custom headers, fuel lines, transmission, etc., etc. As for weight: Coyote weight: 445 lbs. LS3 is right around 430 lbs. Big Deal. Over all weight savings to LS swap a s550 is next to nothing. As for being cheaper then just buying a crate 5.0 keep dreaming.

This is a laugh...


The head of gas engines at Ford gave me exactly what I wanted:

Big Block (he makes a point of that in the video)

With the torque down low (says what I said word for word)

Most performance at normal engine rpms (anyone remember my 1200 rpm diatribe early on).

——————

Plus it has good head flow.


Everything he said in the latest video was music to my ears. He may as well been selling me the engine across the table. Where did I ever say I wanted to beat a Coyote in a drag race? When did I ever say horsepower was a priority? It was all about the torque down low!


Some of you guys must have blinders on. For over a hundred pages I’ve been prattling about the same thing and the man literally gave it to me word for word!


That’s why I don’t want any changes. But that’s just me. Others may want changes but this works out just fine for me. Probably lightening fast as well but I don’t care. As long as it will lay down one mean patch!
