I noticed something in looking in the specifications for the 2021 HDPP.

Cargo Ratings

Reg Cab 4x2 = 76 lb higher cargo rating for 5.0 vs 3.5.

SuperCrew 4x4 = 10 lb higher cargo rating for 5.0 vs 3.5.

Does Ford delete the 36 gallon fuel tank on the Reg Cab 4x2 5.0 to bump up advertised maximum payload? 66 lb is about what the 36 gallon tank adds.

 

The turbo V6 is NOT the universal replacement for the normally aspirated V8.
Snow Plow Prep Package REQUIRES the V8.
HDPP V8 capacity a little better than the HDPP 3.5EB.
A bigger displacement engine apparently can better handle the higher weight loads, at all temperatures, in the long term. Surprise!

 

I'm aware of the snowplow limitation but I'm trying to figure out why the 5.0 is so much lighter in only one Cab/Chassis/Powertrain combination. I was thinking I remembered at one time the 36 gal tank may not have been included with the regular cab.

 

the 36 is standard with HDPP.
I like that max tow is standard with HDPP now on the 5.0.

Okay, I built one on the build and price site and it includes the 36 gallon tank. I'm stumped how they get an extra 66 lb out of the 5.0 in that configuration.

 

Where do these assumptions come from? The only thing we actually know is they do not offer the snow prep with an eco because of disruption of airflow through the intercooler. There are no fans behind the cooler to pull air through. Having a blade in front of the truck means very hot intake air, and very hot intake air is not good. Ford could have easily remedied that issue with... fans! But good lord, we've got enough options across enough chassis and driveline configurations to satisfy a deranged dictator. None of the rest of the eco's need fans down there, and why in the hell would you make them for *maybe* a few hundred trucks optioned each year. Sounds like some don't understand that 95% of snow plow packages are in super duties.

If we're going to make assumptions, it should be that the 3.5 eco holding a 1000lb higher tow and GCWR than the 5.0 says the 5.0 is not the best at higher weight loads, at all temperatures, in the long term. I wouldn't say that, but if assumptions are to be declared as rule...

Around and around we go! You can build any displacement engine to have any strength you need and remove as much heat as you want. Ford could have designed either motor to be the best at both categories, and yet only one gets the highest tow and gross combined weight ratings, which tells us that one may have been built just a bit tougher than the other, but no one outside Ford's engineering teams knows, and we'll never find out because we spend way too much time speculating about petty nothingness.

Both engines are GREAT at what they do. As are the 2.7 and 3.3, and probably the 3.0 as well. A whole lot of tough hearts for our light duty trucks.

 

I read too often posts claiming the 5.0 is a bad engine for towing, no kidding. It colors my opinions/reactions.

 

I thought I read somewhere that the 5.0 weighs about 50 lbs less than the 3.5. Maybe that's where the payload difference comes from? This was a couple years ago, so maybe the newest gen 5.0 is a bit lighter even?

 

A bad engine for towing?

I wouldn't say I see an abundance of posts saying that. What does come to mind is plenty of posts claiming you have to crank the rpm's out of it to pull the load good.
Its no secret that its peak torque is at a high rpm. Thats not a characteristic I prefer, which is one reason I went with the EB. But I dealt with that kind of torque curve on my Chevy vortecs. I had to make my 6.0 LQ4 scream like a raped ape in my 2500HD to pull loads.
And then theres the oil consumption issue.
But a bad engine? No.

Now we will see what cylinder deactivation does to the 5.0. Hopefully it wont turn it into a pile of crap like GM's early attempts.

 

Their is about 50 lb difference on two SuperCrew 4x4 3.31 geared trucks but 40 lb of that is the rear axle.

The 10 lb difference on the SuperCrew 4x4 HDPP between engines is what I would expect. So where did they get 76 lb on the Reg Cab 4x2 (The truck they use to advertise that 3300 lb payload)?
