First it was the V10 come back, then the Eco-boost super duty and now big V8..... I’m not holding my breath.

 

i hate them v10s they are slugs compared to old 460s with some trickery on them.

 

😂😂😂😂..............

 

Please please please don't be direct injection or displacement on demand!!!

 

had an 89 f350 460 which was 1st year? not very reliable but a combination of previous crappy mechanics, modifications, first or second year of efi. 94 e350 460 was much better, always had to fix something on 89

 

whats wrong with direct injection?

 

The heads/valves do not have fuel washing the carbon off the valves and they gunk up and the valves will not close requiring the heads to be removed for a valve cleaning service.

No thanks

 

Fords latest generation DI engines also have port injection so the carbon build up on the valves should no longer be an issue. The beauty about port injection is increased compression ratios.

 

i new that about early DI engines and figured manufactures figured out a solution...apparently DI and PI

ive driven some DI cars that idled terribly and pretty noisy because of the fuel pressure. DI requires high fuel pressure (similar to diesel injection pumps?) and some engines if not all run off the cam. i know VW had/have cam follower failures and if bad enough cause cam damage. hopefully DI issues are a thing of the past

pretty sure a 2020 engine will have modern features for efficiency unlike an old school pushrod engine. how popular are pushrod engines? which cars and trucks have them? what are the engine specs of the ford 6.2L?

 

What he said.

 

I heard from a very reputable source that the new engine will have an option allowing it to run on partially composted grass clippings. That won't be available for order in the southwest US.

 

Like a wood gas military engine. Too cool.

Well, most prominently, the 6.0 gas engine in the Chevy HDs. There is a reason it's been the gasser motor for high duty cycle trucks for the last 17+ years. Adequate power, hilariously cheap to maintain, and will run nearly until the second coming. It is a great work truck motor, probably one of the best truck motors of all time. Less predominantly, the 5.7 and 6.4 Hemi, as well as the Ford 6.7 Diesel are also pushrod engine designs.

The benefit of the large displacement/pushrod design is it's easier to make power lower in the RPM band. You might be gimped a bit on total power output, but with proper gearing and transmission programming, it doesn't matter when you get a nice flat torque curve.

Outside of the HD territory, virtually every single hot rod on the planet runs a pushrod GM LS. The 6.2L in the GM half tons are pushrod. You'll probably hear a lot of people on here go on and on about the Ford 5.0 Coyote making it's way into the resto/racing scene, but for every 5.0 crate motor Ford sells, GM sells 1000 LS motors. And that isn't by mistake - cheap, easy, maintainable power. Nowadays they even get pretty decent gas mileage. Heck, a 700+ HP Corvette (pushrod) will give you 25-30 mpg if you keep your foot out of the loud pedal.

The truth is, since the 90s (with the exception of the last of the 460 big blocks), Ford makes revving (gas) motors. They are generally lacking on the low-rpm range, but they will be happy winding out to 6000 RPM all day long. That's just they way it is, and it isn't necessarily a better/worse approach. I LOVE the 6.2 in my truck. With the right gearing and a decent trans program in the 6R100, the truck doesn't feel sluggish at all. BUT getting a stump puller big block like the 7.3 hopefully will be would also be awesome. In summary, pushrods are great, they are in probably 98% of all trucks on the road, and the idea of moving away from the excellent and dependable 6.2 platform in the SuperDuties to a tried and true tractor motor philosophy with the 7.3 doesn't concern me at all.

 

What about the material ?

"As for the block, word is that it will be traditional grey iron or possibly Compacted Graphite Iron("CGI"). The 6.2L and the 6.8L both use standard iron block, which have the benefit of being fairly cheap while still being very tough. Also, with the introduction of the FRPP Boss 302 and 351 engine blocks Ford showed that they know how to cast a modern, strong, and economical iron pushrod block. Conversely, Ford's use of CGI has been growing over the past several years. Both the 6.7L Powerstroke and the 2.7L EcoBoost feature CGI blocks. It's not out of the realm of possibility for Ford to cast this new 7.3L block in strong, light-weight, CGI."
