Who will swap for the new 7.3 V8!

From the engineer who designed the 7.3 gas. and for anyone who thinks i's a 'drop in' for the Mustang, you're more delusional then Kim Jong-un.

I think this engine will suck for drag racing because it is a truck engine designed to truck things. Again we are talking about the engine as is. Because no variants of it exist, no performance parts exist, we are talking straight up the F-250 version of the 7.3

Because this is a full on truck engine, I wouldn't be shocked if it fell on its face after 5000 RPM

How would it suck for drag racing when it's likely going to have 440hp ish and over 500 lb ft of torque? If that's the case, then the coyote also must suck for drag racing, as it has marginally more hp but a shit ton less torque.

And why do you seem to think you need to turn high RPM to be successful at drag racing? 5000 RPM would be absolutely adequate if paired behind a 10 speed transmission that allowed the engine to stay right in the meat of the powerband.

People like staying N/A, as it is mostly cheaper and less risky in the long run. However, many on this forum have already shown you can have safe power with boost into the 700whp range.

Safe is relative. A 700whp coyote is NOT going to last 200k miles. N/A is far more reliable both short and long term.

I am not talking about engine potential. I am talking about going the fastest for the least amount of money. The 427 with forged internals is going to be more stout than a stock 7.3 with stock internals set up for truck duty.

The 7.3 has a forged crankcase and is going to be stout as hell in stock form. Every article is touting how durable this engine is going to be. A 427 has none of the new technology this engine carries and has a weaker block. It has small block bore diameter and spacing, meaning worse cooling and far smaller valves.

So you add cams and mess with it enough to get 600hp N/A. All that just to be killed on the track by a guy running a blown 5.0L with no internal work. It takes more than a good 60ft to win a race. Like I said, I understand how some can be excited over it, but it will take a lot of time and money to make it into a successful track engine in an S550. The people who will do it are going to do it just to say they did it.

This is a OHV engine, it takes a single cam, not "cams".
Let's not forget either, blowers aren't exactly cheap...and they add a good amount of weight over the front end.
It will no doubt take time though, I will give you that. It's going to require someone that already has an engine/transmission-less S550, or someone that is able to find a hell of a deal on a salvage.

By whom? See. This is why sources are required. At this point you're just repeating something that Fatguy said without sources. In fact, the source has stated that the 7.3 will be longer as it has larger bore spacing.

Yes... sometimes people do things just for looks.

While anyone who knows what they are looking at just laugh, and laugh.

Not repeating Fatguy. I'll see if I can re-find the article. I knew I should have cited it. The 7.3 will be longer, but not by much.

Love the video. Didn’t say anything about fitting it in the Mustang though. What he did say:


1. Definitely a “Big Block!”


2. High flow heads!


3. Torque down low. Word for word as I said it here: TORQUE DOWN LOW!!!!


Also: Raptors can close it out on the 76ers tonight!

 

[WildHorse]

Because it's never gonna go into a Mustang.

 

[Fatguy]

Because it's never gonna go into a Mustang.

He also said the engine was designed to deliver maximum performance at the rpm ranges typically used just like I talked about earlier.


What’s not to love!


So it seems to be coming down to fitting it in the Mustang. The high flow heads was a must as I didn’t talk much about it but opens the aftermarket door to serious horsepower within the engine’s limits.

Aren't you guys running out of lube yet

 

[Fatguy]

Aren't you guys running out of lube yet

Nope.

The engine is everything I wanted. And it looks like this baby may be putting out more juice than people around here think. He bragged about it (the Ford manager above) a good sign. It could put out more horsepower than the Coyote.

Godzilla got the juice now man!

Got 50 gallons of lube left in the original 55 gallon drum - lol.

When people get tired of piston slap and such.
Engine swaps will start to happen a bunch more.
The S197 was in the same boat.....but now it's common place.

Those who don't will just trade off for a newer car and it may not be a Stang.

You say so much stupid shit, it continues to blow me away on the daily. You make shit up as you go along and it's all literal bullshit. S197 engine swaps are not common place.


I'm glad to see this thread is still a dumpster fire. I wouldn't expect anything less from people who don't know shit about cars and don't even own the car.

Absolutely hilarious that a few knuckleheads still think an iron block truck engine designed for towing is going to be a good fit for the Mustang. Hell, it isn't even a good fit for the F150 because the 7.3 is designed for heavy load towing and not light duty application. How many times does that need to be said before it sinks in?

How is it possible that people are actually stupid enough to believe that a truck engine designed for towing will be a good swap and improve performance?

Only a moron would attempt this swap because it would cost tens of thousands of dollars to kill the Performance of the Mustang in every aspect.

Slower than a V6, check
Handles like a 1970 Lincoln, check
Maintenance nightmare, check

Who is going to want a 70k Mustang that is slower than a V6 and handles like a 1970 Lincoln?

Fatguy already said he isn't interested in doing the swap so I guess that leaves Mill and Erik?

News flash guys,. it's an iron block truck engine that is designed for towing, it's too heavy, probably won't fit, and would suck ass even if it does fit.

Awaiting a stupid response from uninformed knuckleheads who think the 7.3 is going to slide right into the Mustang and start winning drag races.

Actually I still have to leave the possibility open as that latest video had that Ford manager literally mouthing everything I said in this thread. The big hit was confirmed “Big Block” which is what I wanted. Confirmed that all the performance was at typical rpms used which I’d positively want to have. I don’t believe these guys that say they drive their GT at 4500 rpm and up to go to Costco and crap like that. They drive like 1200-2000 which is where this engine delivers horsepower and especially “the torque down low”. Horsepower near or exceeding the Coyote at realistic engine speeds.


But the performance does not matter as much to me and Millhouse. It’s the torque down low!


Sure I could change gears but still a V6. Could buy a Z06 C6 Corvette but many question the true Big Block designation. And here in Canada you are looking at around 45,000CAN. The Corvette seems the most desirable but the latest specs seem to have moved the 7.3 back into contention. Now it’s actually fitting it in. The Corvette is just cutting a check and replacing valves and guides. However if someone actually sets up shop doing this swap - I could actually pull the trigger on it.


Saying it’s a truck engine endears me to the motor so... The iron block swipe is a joke as every car I have owned prior to the V6 was a V8 iron block and somehow I survived to talk about the “horror” of it all.


Calling people morons and worse and making statements about performance on an engine who’s specs are not even out is also talking out one’s ass. It doesn’t increase the credibility of what you say. I don’t name call, but that’s just me. Realize that there is a human being at the other end of the connection. You would never talk like this to them in person - would you? I have skin like a crocodile, but the others may not - just saying.


And you didn’t t say this above but all the calls for locking and trolls and all that seem to apply to those guys also. Just step back and think about that. But it does not matter. A new big block with decent numbers is about to come out and answer all questions in this thread. This thread is all about automobiles and hotrod swaps and a new big block Ford engine that potentially could fit into a Mustang is a real talking point on a forum like this. Locking the thread is just ludicrous.

It's a heavy duty truck engine designed for towing and there is nothing you can say that will change that fact.

A Heavy duty truck engine designed for towing and dropped into a Muscle car will make it slower not faster. It will kill the handling of the car not make it better.

Somehow that makes it a hot rod? What a load of horse shit. Taking a car or truck and making it better, faster is hot rodding.

Are you honestly suggesting that the 7.3 will be faster than a 5.0 in the Mustang? You are fucking mad crazy brother. Do you know more than Joel Beltramo, manager for V-8 gas engines at Ford?

"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."

You change your tune on a daily basis to keep this thread going and it's starting to make a mockery of M6G.

The 7.3 swap is something you want to do then do it, no one is going to stop you from destroying a Mustang.

I will continue to call it a stupid idea.

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

You keep on say it's a heavy truck engine, but you have no clue as to what it's going to weight. You don't seem to realize that this isn't a truck engine of old. It's going to have aluminum heads, aluminum roller rockers and a plastic intake. That Iron block you keep thinking is going to make this a boat anchor is only going to add 75-100lbs over what it would be if it were aluminum. This engine is going to be no more than 100-150 lbs heavier than a coyote. That is 0.1-.2 worth of weight in the 1/4 mile. If it has anywhere near equal horsepower as the coyote, that is going to be more than made up for by what it will allow the car to 60' with all of the extra torque it carries.

Think of it another way. This engine is likely going to putting out the same (if not more) horsepower as the current camaro. It's going to be producing a ton more toruqe. The current camaro has been eating the mustangs lunch on 60' and 0-60 times. This 7.3 would be very competitive with a stock coyote.

How some of you don't see that this may very well make an s550 faster (1/4 mile) is beyond me. It doesn't matter that it's a truck engine. It doesn't matter if it runs out of breath at 5500 RPM. Horsepower is Horsepower, and Torque is Torque.

It's interesting to see all of the negative perspectives on engine swaps in this forum. If you head over to other mustang and automotive forums, engine swaps are common...everyday occurrence. This thread wouldn't have nearly the amount of naysayers. It seems many of you need to get out and turn a wrench. Hotrodding may not survive the wrath of the millennial.

Do you know more than Joel Beltramo, manager for V-8 gas engines at Ford? What is interesting is you and others think you know more than everyone else on the subject, including Joe. You are ignoring the FACT that this engine is simply not designed for Mustang or light duty and therefore will SUCK ASS in a Mustang.

"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.

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.

This has to be of the most ignorant comments I've read on a forum.

Just because an engine is not designed for a vehicle does not mean that said engine can't make that vehicle faster. It's absurd what you're saying...really. The only "FACT" you have stated is that the 7.3 is not designed for the mustang. This has nothing to do with how the mustang can before with the 7.3 engine. It's mind boggling how you're trying to infer such...really.

"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.

Get back with me when Beltramo says the mustang will be slower in the 1/4 mile. All he is saying is the 7.3 is likely going to be a PITA to shoehorn into the coyote, and it's going to throw off the vehicle dynamics. You know what else throws off vehicle dynamics? A 75-100 lb blower or turbo kit that people bolt on to the coyote.

Again, when you have a fast shifting10 speed transmission, that low re-vving nature DOESN'T MATTER in the 1/4 mile.

No one here (myself included) has any facts to support weather a 7.3 swap would be advantageous or detrimental to the S550's 1/4 mile. There are no real weight specs, no horsepower specs, nothing. No conclusions can be made. There is however evidence that suggests the 7.3 can be competitive, by taking current OHV hp/l figures and applying them to the 7.3L. Likewise, weight can be inferred by current OHV engines. This evidence suggests the 7.3 can be competitive without modification in the 1/4 mile.
