They should make it an aluminum block as standard. Less weight would help with fuel efficiency Exactly How about making a challenger 7-10% smaller. The damn things are huge

YES. I hope they keep the 2-valve layout or they really won't be able to get away with calling it a Hemi anymore, purists still whine the Gen 3 isn't a "true" hemi (yeah whatever) If they ever get around to it, the next Challenger is supposed to be on a smaller platform shared with the Alfa Giulia. Maybe they're waiting for this new smaller Hemi to get developed so they can use that, Hmmmmmm They should make an aluminum-block version in a throwback 5.2L, would give new meaning to "smoking Mustangs with a 318" heehee

Dual over head cam similar to the LT5 but cross flow valve head, like the modern Hemi, 4.7/5.2ish 2020/2022 4.0-4.25 bore spacing. Would be a logical next step. The power Tech 4.7 was going to grow to a Dual Cam, 5.2 before DC started to have money issues.

they make less HP (385HP) than a smaller 5.7 hemi (395 hp) with all of its "pushrod fuss" I don't get the ferd fuss I guess and they have the same junk cam phasers that start dying around 125,000 that the 5.4 pile o junks had in a nightmare package to work on so I'll pass a 6.2 in more than one ways.

5500 RPM redline in the Ford 6.2L and it's SOHC? What's the point? That's the same as a 5.7 Hemi with those 'antiquated' pushrods...

How about you take off your socks and count up the number of moving parts in a SOHC vs a pushrod V8 valve train. Then ponder the inertial mass involved in each and recall that a lighter valve train can be opened and closed quicker allowing more area under the curve. Then think about that pushrod pinch in the LA intake track and it's complete lack in a SOHC design. Want to keep playing?

how bout the 400ft of timing chains that inevitably stretch over time and are expensive and complicated to replace (think 4.7 dodge, 5.4 ferds, 427SOHC ferds, 5.7 tundras...) there is a whole plethora of engines plauged by that insanely long chain requirement. And as a bonus the extra valves and everything still don't help the head flow anymore than an apache/hellcat/BGE head.

400ft of timing chain, get real. If it's all that complicated and intimidating then retire.

I do em for a living and see the look in peoples eyes when you tell em how much its gonna cost to fix that garbage without even having high miles on em. They cost twice as much and don't last near as long with no benefit, especially in a truck engine. Sorry but its just a cool novelty that ain't worth the cost in a production type engine.

I knew that my comments would not go un-carped upon. Did I use the word "antiquated" anywhere?
I don't give a poop about cam phaser problems, I am not buying a ford pickup. Obviously if one wanted to build a hotrod version of the engine the redline would be higher. So what? So pushrods work to 11,000rpm. So what?
You guys fire off comments without doing the research. That's your right, but it doesn't make you more knowledgeable.
The original question was which direction would a new version of the Hemi go. My suggestion was that it might go in the direction of the 6.2, as the rocker arm arrangement of that engine very closely resembled the rocker arm arrangement of a Hemi or, for that matter a Toyota 20R.
The reason I was familiar with this is my recent trip in a new pickup that had the 6.2, which was quite impressive to my 318-powered self. And I figured out that the engine was OHC from inside the cab, from the sounds it was or wasn't making.
End of rebuttal.
R. Sorry I wasn't actually trying to argue with you though I guess it did sound that way, my comment wasn't aimed at anyone in particular and I do get your point. I'm simply saying if Ford went through all the development to make a SOHC truck engine why does it only rev to 5500 RPM? And have basically the same output as an engine half a liter smaller in displacement (5.7 Hemi)? It's like the modular engines, with all the advanced technology they had they should have been on another level vs. GM and Chrysler but were basically mediocre throughout their entire run. They had all the problems of modern engine technology with no real advantages over the competition. I don't think the 6.2 is a "bad" engine I'm just disappointed it can't do more (and yes I know Ford has the special high-output version as an option on the Raptor). Pushrod arrangement does create a lot of extra heat at high RPMs and has more friction but it keeps big-displacement engines more compact and lighter. I just feel like with pushrod engines like the Hemi and LS being as good as they are, any future V8 from Chrysler or GM that does have OHC better take full advantage of it and really raise the bar. Or at least just Chrysler lol

That's how I see it, using technology so on paper you're keeping up with the industry but in practical use there is no real benefit. And apparently a few fatal drawbacks.

No mention of the big displacement pushrod v8 that Ford's developing for trucks?

I think you're talking about the 7L? Pretty sure it's going to be a DOHC engine, supposed to be around the 500 hp mark.

The pictures I've seen are of a pushrod motor.

I own some modular Fords; they're nice and scream up top but, the lower end grunt of a pushrod motor just can't be beat. Although some of my modular Fords are faster than some of the pushrod motor cars that I've owned and own currently, they're just not as much fun in stop light to stop light situations which is what is more frequently experience when driving cars on the street. It's interesting the old pushrod 5.0 had more grunt than the 4.6 even though the stroke was literally a half-inch shorter. I'd imagine the modulars are better suited to road course stuff vs. drag racing...?

Thank you Dave, for restating that oft-forgotten fact.
Other thoughts: Ford's Modular engine represents a bad bet on the future of IC engines. They thought they'd be getting much smaller. By using a bore spacing of 100mm, they effectively limited bore size to 3.66 inches. As a result, the 5.4 and 5.8 Modular motors have a stroke of 4.165 inches, longer than a 454 chevy or 472 caddy. The 302 was never known as a torque engine, and the 4.6 is even smaller. It's a gutless wonder like the chevy 4.8 LS motor.
Also, the point about DOHC engines taking up space is valid. I remember the first time I saw a 5.4 ford crate engine...Doggone, that thing is huge!

One thing not mentioned is the price to produce. IMO the hemi will probably get replaced with a V6 trurbo and the V8 will only be offered in the 2500 and up series. The Fords are more expensive to produce. Matt *Was going to be replaced. Those silly 55mpg fleet average rules by 2025 are getting rolled back. It'll be made official in March, and for good reason. FCA didn't have a hope in he11 to meet them by selling Jeeps, Rams and muscle.
