all of these puny 3 digit numbers...

Understand? Sure. I've worked on many. They're simple. That's their only redeeming quality. Everything else about fuel injection is better. Everything. Torque, power, drivability, efficiency, reliability.

I like the enthusiasm the OP has for the push rod design. This 7.3 will have a lot of torque, but engines for cars are not designed for 1,200 rpm. No one in a Mustang spends their time driving around at 1,200 rpm. The lowest my 18 GT A10 will settle while cruising is generally around 1,400-1,500 rpm or so (I don't remember the exact values). RPM at 60 mph with the 3.55 torsen read end and the A10 is about 1,700 rpm.

I bought my first car, a used '87 Camaro Z28 in 1995, that I put a 350 tuned port injection into (the car came with a 305 TPI which wasn't too bad), so I know low end torque fairly well (those long runners). But that car was fairly slow by modern standards.

I'm amazed at how much power the old big blocks don't have. 283 rwhp, but rated at 425-450 crank hp?? I know that is gross power, but WOW. I'm surprised. That's in reality only about 335 net crank hp which I think would be around 375 gross hp. Sheesh - over rated much?

The 5.0 Coyote makes significantly more torque than those old Chevy SS/Corvette big blocks. Better gas mileage, smooth, and low emissions. Not sure what the lore of those old big blocks are for anymore - other than nostalgia.

Should someone tell this dude that the common usage for 'Godzilla' in the car world refers to the Nissan GT-R?

You actually got me thinking about how Godzilla was trademarked so I looked into it. I have one registered trademark and it took me 7 years and in the end some pro bono work from a trademark lawyer to finally register it - never again (no cut and past applications as they change the books and terms constantly. Job security for lawyers). I use it in three small corporations I have. I have another Logo for two more corporations that is not registered so you just see the “TM” and not the “R” in a circle. That is the way to go paragmatically. But a trade mark for a movie monster does not necessarily prevent one from using it for a car engine. A lawsuit was dropped against Honda for example. I think Nissan is trying to trademark a variant of Godzilla for an upcoming product.


Long and short is that we can us GODZILLA for this engine until some court says no. And if people just let it be they loose their right to the trademark. Plus many trademarks only have dominion in specific regions trademarked. So the issue of who can use Godzilla for an engine is still up for grabs...



LONG LIVE GODZILLA!!!!!

Ok, 1200 was just to grab attention. In later posts I set the range to 1200-2000. Nothing wrong with nostalgia and Godzilla could beat the 5.0 in horsepower and massively in torque. We shall just have to wait...

.... could beat the 5.0 in horsepower and massively in torque....

Prepare to be disappointed. If the 7.3 beats the power of the 5.0, then don’t expect any torque until 3500+ rpm.

 

[Fatguy]

And here is an open call for those who mock me.


Have any of you ever seen engine advertising that states horsepower and torque ratings at rpms people normally use? What good is maximum torque or horsepower at 5500 rpm if you only go there for a second three times in two years?

Sounds impressive in the advertising but is a lie for day to day driving. My way is more honest and practical...

 

[engineermike]

Dumb question fat guy....when you floor it, what does the rpm go to? 1500 or 5500?

 

[BmacIL]

if you only go there for a second three times in two years?

Bro, do you even car enthusiast?

Hey, since most driving is done at 0 to 1/4 throttle, maybe they should advertise power and torque at part throttle, right?

The codename is legitimately Godzilla though.

60 year old car enthusiast.

60 year old car enthusiast.

My dad (older than you) isn't a car enthusiast and sees that kind of RPM far more than a few times a year. Most 60 yr old car enthusiasts I know are still actually enjoying the car (going to racetracks, enjoying the occasional highway blast, etc). I don't get the garage-queen dad's who never drive the cars, and when they do, only to car shows and never push them beyond a snails pace. What a waste of a machine. Buy a picture of a car if you're going to do that.

Those HP and T curves are at WOT. Nobody drives around at 2000 RPM at WOT.

The Coyote has plenty of low end torque to cruise around town like a grandpa. And it has lots of HP and T in the high RPM range to go wild if the desire or need arises. You can cruise around town at low RPM very easily with the Coyote.

Now if a Coyote vs this new 7.3L V8 were in an F-350 with a 2 ton load then the 7.3L might be more suited for the job. But also realize that the transmission and differential grearing will be changed in a big truck like that to match the engine's power curve.
