Every manufacture eventually comes up with a modern V-8 that shares the architecture of the old FE series of engines.

I sure hope the bore spacing is at least 4.45" and the deck height of 9.2' or more.

Bore space is the same as the current 6.2, 115mm or 4.527inch. Bigger than LS and similar to Hemi. Not sure on deck yet, but its supposed to be lower, narrower and lighter than the v10 it replaces.

Right now its confirmed for super duty and commercial trucks. Rumors are there are versions of it slated for Raptor and high trim F150. Pray hard enough and we might get a new boss 429

More specs and highlights;
4.22 bore
3.98 stroke
Weighs about 570lbs (similar to iron LS and hemi)
Forged Crank
Piston cooling oil jets
Roller cam
Roller trunnion rockers
Beehive springs
Port injection (for now) with the injectors in the head
Cast stainless manifolds

I'm excited about this engine. Surprised there isnt more interest here.

They are being coy about power numbers, but its an interesting look.

Man, if we get a Boss 429 back, that would certainly be something special.

More likely the boss will be a toaster-plugin model with a turbo 3pot. =/

Not sure why all the hype from the car guys over this motor. Much heavier and same hp as the current 5.0.

Makes sense for the truck but not sure I'm as excited as everyone else. Fuel usage vs the 6.7 is going to make the 6.7 a better choice for most even though it's more expensive

Simpler is better. Heavy is what is required when aiming for massive bottom end strength. Why do you think the 2nd gen Chrysler Hemis are the end all be all for maximum HP out of an automotive design engine?

No clue why anyone would want this over a diesel. It would be cool to see it turn into a performance motor.

Because of the hemi head. No idea what you are getting at.

As for this engine, it is neither a hemi head or even a canted valve design from what I have seen. It does have six bolt mains and a forged crank so I guess it can take a ton of power. The ports in the head are promising but the valves are long as shit (heavy) and the valve train looks completely non adjustable. It seems like just another towing engine (V10 modular) where Ford made it for the cubes and the torque. If they make different heads for it I guess things could get exciting. I can't ever see them putting this in a mustang but I can see them putting it into a new Lightning.

About this vs diesel, not everyone needs all the power of a new diesel. Also, gas is such lower cost overall. Engine option $800 vs $8000. The maintenance cost of gas is much lower. Fuel costs should be a wash since gas costs less and with a new 10 speed it'll still get 15ish mpg.

As for performance, give me this all day over a coyote as the start of a build. Narrower. Easier to work on. Big cubes. Whats not to like?

Believe it or not the Hemi head is a shit head for making power. The reason the Hemi is the end-all-be-all for making power in an automotive engine it's because the bottom end is strong enough to not explode instantly when you hit it with Nitro methanol. No other automotive engine that has ever come out of Detroit has had the bottom end strength of the 426 Hemi. This new 7.3 Ford may have that kind of bottom end strength.

Yea, this is bullshit. As is usual for your posts.

Go fuck yourself.

What part do you think is bullshit?

They tried to run the Ford 427 FE series of engines in Top Fuel back in the sixties. The engine block wouldn't survive a single pass. Same thing with the Boss 429 and the big block Chevy. The earlier 392 HEMI had buckets of bottom end strength also and it was copied by the aftermarket and used in Top Fuel for many years.

For making power no conventional combustion chamber beats the pent roof four valve chamber and a true hemispherical combustion chamber is as bad as you can possibly make a chamber when it comes to brake specific fuel consumption.

The FE 427 cammers were pretty competetive but Ford failed to support them the way Hemi got mopar support.

The Shotgun 429 was never real competative because it came out after hemi had years of development, support and experience. Then Ford pulled the plug on all racing shortly after thereafter.

GM didnt officially race much in the 60s so the BBC faced similar support issues, though without a hemi style head it wasn't going to be competative any way.

To say these motors just exploded and the hemi didnt and thats the only reason hemi was successful is intentionally obtuse.

Jeez! Ford hasn't even put it in a truck yet and it already has "ticking" issues. At least that what the narrator says at the beginning of the video.

I like to say the FE engine were my first love and I have owned a ton of them. Even the best 427 blocks what rip the main bearing webs out of the block nearly on every pass in Top Fuel. There was simply no getting away from it, it was not heavy enough. They were extremely competitive in all other forms of racing. The Hemi not dying is what allowed it to continue to evolve. Its bottom end strength is what made it the engine it is today and no other engine to come out of Detroit has the bottom end strength of the any of the hemis. Even the 92s were built like a bank vault. Hemis were also pretty common in the junk yards back in the day where as the specialty for 427 Fords or big block Chevys were not.

Never popular, complete bullshit design with a pure shit cylinder head. They did use large journals on the crankshaft so if somebody had wanted to they may have been able to get some power out of it without it breaking. I'm not sure if it had cross bolted mains or a steel crankshaft though. Without those two features it would have been an uphill battle.
