It would be pretty hilarious. Even better with boostI'm waiting for my S550 Boss 429....
Aluminum block, 7k rpm redline, aggressive cam, A10 trans, 550hp 575tq....

As some are aware, Ford Motorsport have released an iron block coyote to cope with boosted applications beyond 2000hp.It would be pretty hilarious. Even better with boost
With hardware changes for high rpm it would easily go over 700hp. No blowers or intercoolers means it would probably be on par in weight to Predator. What's stopping Ford producing this in alloy?I too am awaiting for the Boss 429 Mustang. Rpm red line may be closer to 7500 RPM for a high performance 7.3 liter V8 the way that engine is designed.
Cost and demand. Iron is cheaper...and stronger. Ford also stressed how they wanted an engine that was easy to work on and easy to rebuild for fleet vehicles.

I really think Ford intended this engine to be primarily for work trucks in the F-250 and up categories and fleet vehicles...not for the Mustang. It seems to be a more affordable way to get the torque and power needed without running chain driven dual overhead cams with lightweight high performance like the Coyote and VooDoo. The pushrod design is meant to be simpler and more affordable for working vehicles. Especially since Powerstrokes have all the extra emissions equipment the 7.3L doesn't need. Also, the cast iron block is meant to provide long term reliability with lots of low end torque using the forged crank. I just can't see how this engine was in any way intended for the Mustang.What's stopping Ford producing this in alloy?
It still makes you wonder how much effort it would take to recast the block in aluminum for car use. The original modular featured an iron block, and we know where that eventually went.Cost and demand. Iron is cheaper...and stronger.

It wouldn't be difficult, just expensive. They would need a business case beyond throwing it in a Boss mustang.It still makes you wonder how much effort it would take to recast the block in aluminum for car use. The original modular featured an iron block, and we know where that eventually went.

It's still 100 lbs over the front wheels, which isn't good for anything except making for heavier understeer and longer stopping distances. Even forward acceleration takes a hit, all the way up to whatever speed it stops being possible for engine torque to overcome tire traction.And....for the Foxbody crown, that engine allows direct fitment of the 10 speed auto out of the GT without any transmission tunnel modifications.
I'd like to stress the point that the 100 lbs difference between the coyote (if proven to be true) is is pretty small. Hell, throw an iron block on the coyote and it's now the same weight as this 7.3 engine.
NeverOh God let it die!
You are talking from only one vantage point. There is a reason this engine will be in future swaps....and it's a similar reason Ford is going to start offering an aftermarket iron block (+100lbs) for those with a coyote engine.It's still 100 lbs over the front wheels, which isn't good for anything except making for heavier understeer and longer stopping distances.

It makes perfect sense if you want to go bigger than 5.2L (aluminum block limit). There is obviously a demand, and the weight is inconsequential for those looking at big power. The iron block can go all the way out to 5.6L.Which makes zero sense as to why it's being offered so far because sleeved Coyotes are already handling 2000 horsepower at the crank. And living to tell the tail and do it again and again.
What is crazy though is the price of these blocks.
"Ford Performance expects the block to become available to customers starting in the first quarter of 2020, priced between $5000 and $6000"
