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.

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

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.Originally posted by racrguyWhat's your beef with NPR, because their listeners are typically more informed than others?Originally posted by racrguyVoting is a constitutional right, overthrowing the government isn't.

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?1971 Ford Torino - Time to go bigger and better.

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.Originally posted by racrguyWhat's your beef with NPR, because their listeners are typically more informed than others?Originally posted by racrguyVoting is a constitutional right, overthrowing the government isn't.

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.Last edited by svauto-erotic855; 02-11-2019, 10:26 PM.Magnus, I am your father.

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.1971 Ford Torino - Time to go bigger and better.
