Interesting discussion here. I think the main reason we saw the demise of the straight 6 engines was the uneven fuel distribution with those log manifolds. Emission constraints couldn't be met, so they went away.
Not to hijack a Ford gasser thread, but has anyone looked at the numbers on GM's new 6.6 gasser?

At the end of the day torque is what moves big loads and 475 doesn’t even get in the game compared to my 900+ when it comes to 20,000 +/- trailer and these small hills we have here in the West.......I’ll stay with my diesel

Interesting thread...I’ve had 4 diesel Pickups...2 duramax and 2 powerstrokes...the 1st dmax was an expensive truck to maintain...and the only one that had a failure (injection pump) i nver bought a Cummins because several friends of mine had tranny issues and downtime. A couple of them have switched to ford and chevy...none of their stock configured cummins have anything on the new dmax or powerstroke....IMO...I went with the 2019 powerstroke because my 2013 was such a good truck....i like having 900 pound ft of torque @ 2000 rpm...and it delivers 19-20 mpg running unloaded....no gasser that i have come across will pull with it without drinking way more fuel and screaming at 5000 rpm...I did get the extended 100% warranty to 150k for under 5k....it pulls our 303rls real nice....and the mirrors, lighting, seats, ergo, and power make this truck really fun to drive with and without the 5th attached. I’ll stay with diesels!!

I agree but the ecoboost can't handle the continuous load that some of the commercial guys will put on the engine. Ford could make an ecoboost version for the F250, F350 and set the power around 400 hp and 600 lb feet. With the torque curve of an ecoboost it would be a great towing truck for the lighter loads

It should handle the load just fine if it can do as good as this one, and this was a few years ago so the new ones should be even better.

I have had four of 'em. I got one of the first '11's when they come out, also a '13, '16 and now a '17. Notice the part in the video about the glowing manifold? Well that's the problem. These engines runs so hot the manifolds warp and start leaking. If you tow heavy and do a lot of it the manifolds warp. Aftermarket is now making ceramic coated exhaust manifolds to combat this problem.
Now imagine, instead of a guy pulling a RV all summer but a commercial guy with a steel bed and carrying thousands of lbs of tools.....

I just realized something. It has 105 HP more than my 04 6.0 and only 85 lb-ft less. Given current fuel/gas prices this could be my next engine, But I will wait to 2021 for them to get the bugs out and see fuel mileage. My 04 6.0 does fine pulling my 220RK so this could be even better. 04 6.0 specifications is 325 HP and 560 lb-ft torque

Just keep in mind that its not just about the peak number. Those gas numbers come at the top of the RPM range while the diesel numbers peak at a much lower RPM and typically have a flatter torque curve. Regardless, towing lighter, gas at the very least is a viable option and maybe the better option.

Everyone always states that the diesel makes its power at a lot lower RPM than a gas engine does. This is a true statement, sort of. If you are just looking at the actual numbers where the engines make their power, then yes, that is true. But you have to actually look at the entire RPM range of both engines and where that engine is making its power, from 0 to redline. I think you will find they are making their power at about the same area, a little past halfway. People say they don't like gas engines because you have to have them screaming at 5000RPM for them to make power. Max HP is always up around redline so isn't a diesel screaming near its redline when it is making max HP? Don't you have to push any engine to near redline to get it to make max HP? But when we are towing aren't we more concerned about torque and keeping the RPM in the torque curve so it tows best? A new 6.7L diesel with 3.31 gears and 18" tires will turn 1528RPM at 70MPH, 3.55 gears will be 1639RPM. The new diesel produces its best torque at 1600RPM. The new 7.3L gas with 4.30 gears and 18" tires will turn 1985RPM at 70MPH. If you look at the torque curve this engine is producing around 425ft/lbs of torque at 2000RPM then climbs and flattens out at around 450ft/lbs and 2500RPM and holds that until after 3000RPM where it starts climbing again to its peak of 475ft/lbs at 4000RPM. After that you will actually see a drop in torque until you hit the max HP value at 5500RPM. Lock the transmission into 9th gear and you will be turning 2174RPM, 8th gear and you will be turning 2678RPM and 450 ft/lbs of torque. Seventh gear will give you 3182RPM. Sixth gear will give you 4033RPM and your max torque. When climbing a hill don't you want to be in the area from 2000RPM to 4000RPM to get the best torque numbers for pulling a hill? That is hardly screaming for a gas engine, but a diesel yes 4000RPM would be over redline. My dad had an older 7.3L diesel that did not have as much power as this new gas engine does and he never had any problems towing a large camper all over the Rocky Mountains so I would imagine this engine would do just as well. Will the new super diesels pull the hills better and with power to spare, sure they will, but I think this engine could easily handle a 15,000 to 16,000lbs fifth wheel with a dry pin weight of 2500lbs in any terrain and have the payload to do it where the diesel would have to be a DRW to have enough payload. The F350 4x4 with the 7.3L and 4.30 gears is rated at 20,200lbs for fifth wheels and the 6.7L diesel with either the 3.31 or 3.55 gears is rated at 22,000lbs, just 1800lbs different. They both are rated at 15,000lbs for conventional towing. I would hope that Ford wouldn't rate this engine at 20,200lbs if it wasn't capable of towing that load anywhere in the United States in all terrains. It might climb the hill slower than the diesel but I think it will still climb the hill with ease if you use your gears and keep it in the RPM range for best towing, say 2000 to 4000RPM. I do the same thing with my 2015 3.5L Ecoboost towing my 8100lbs camper when I am climbing a long hill, I kick the transmission down to the gear that puts me in the best part of the torque curve and it climbs the hill with no problems without losing any speed. I always stay below max torque when climbing in case the situation calls for more power I can kick it down a gear and get more torque out of it. I see using the same technique on this engine and it should climb any interstate hill. It wasn't that long ago that if we had an engine that made 475ft/lbs of torque we were excited and figured we could tow anything anywhere, that was a lot of power. I think we have gotten spoiled by having engines that are overkill and it has been caused by the manufacturers trying to outdo each other and not an actual need for engines that strong.
I found this torque curve for the new engine. Even though the max torque is at 4000RPM it builds torque fast at low RPMs and holds it there. It looks like by 1500RPM it has over 400 ft/lbs torque. With the 4.30 gears it is rated at 20,200lbs for the 4x4 and 20,600lbs for the 4x2 fifth wheel towing and the 6.7L diesel is rated at 22,000lbs for the 4x4 and 22,400 for the 4x2. From what I can figure out on Ford's horrible payload charts it looks like it will have over 500lbs more payload than the same truck with a diesel. Now I am going to have to rethink the gas vs diesel issue because the increased payload on a SRW 4x4 with that torque curve is very tempting. I can get the trailer my wife wants without having to go to DRW. Its only money if I choose wrong

A late model 6.7 long block through Ford Parts has a MSRP of $7000, and it can be bought online for $6000. Do you think the nephew might have been taken advantage of if his engine cost $15,000? It's just not that big of a job to lift a SuperDuty cab--maybe a 1 hour job--for any shop with an overhead lift.
And by the way, Caterpillar no longer makes any truck engines of any size. They bowed out when the EPA regulations caused them so much trouble. They're putting their engine and engineering into off road equipment.
