I am not sure what you are trying to say. I am not surprised that you have never seen a drag race truck hooked to a pulling sled.
The NTPA unlimited pulling tractors don't run diesel they run spark plug engines(mostly methanol) but similar power can be made with a gas engine.
Gas engines are more powerful than diesel engines in a size that can be fit into a pickup truck. Not an opinion just a fact.

Link to this fact? Now remember, the engine has to run mainly on gas not meth. We are talking about building the most powerful tv to drive on the street.

Just go to the NTPA look at the unlimited pulling tractor points I checked to see what the top 5 in points were using and they were all running multiple big block roots blower alcohol engines. The rules allow them to use any engine they want and any number of engines so long as they meet the weight limit. Most likely the alcohol is run as much for fire safety as it is for power. A gas engine and an alcohol engine can make similar power.
Given the money it would be easy to make a big block turbo pump gas motor making 2000 horsepower and similar torque. That is enough power to take 80k lbs 80 mph up a 7% grade. I can't think of a tow vehicle needing more power than that.

I would love to see you build one and it be street-able. Not going to happen.

Why would it not be street-able? A 932 cubic inch turbo motor with 2000 horse is not a very highly tuned engine. Turbo engines can make the power with much more mild characteristics than a naturally aspirated engine.

Just curious. If gas is the way to go for pulling heavy loads, long distances, over varying terrain, for a long time, why are semis diesel? There used to be gas semis back in the day, but I haven't seen one for years.

Yes, fuel economy. For an OTR truck fuel is a large part of the total cost of ownership. It really doesn't matter how fast they can climb hills or anything else. They just need enough power to get the job done. They don't care if it burns diesel, gasoline, or coconut oil as long as the total cost of ownership is less.
But then that's for a truck that's on the road 8 or more hours a day, every day. That's not something I'm looking to do in a recreational endeavor. So for me anyway, any comparison to OTR trucks is apples to cumquats.

Personally, I don’t know much about building custom motors. That’s not my thing and it’s way above my pay grade. So when I made my choice I had to look at what was available. I’m also a GM guy (always have been except for a 94 Dodge Ram) so all I really know about are Chevys and GMC.
When I compared my truck equipped with the Duramax side by side with an identical truck equipped with a 6.0l (except the 6.0l had 4.10 rear end and the Duramax has 3.73), the Duramax won out in every category related to towing except payload (because of the extra weight of the diesel)…horsepower, torque, max GVWR, max conventional trailering, max 5th wheel trailering, and GCWR. And from what I’m seeing on this and other forums the diesels are getting better mileage towing.
I also understand the initial cost of the diesel, the added cost of fuel and maintenance makes the diesel more expensive to operate on a day-to-day basis. But…my situation is a little different than some. I’m retired so I’m not driving back and forth to work every day. If I were I might have decided differently. I bought this truck to pull my camper with, but I still use it as a day-to-day driver. I also have another vehicle I can drive daily.
Like I’ve said in other posts, FOR ME, based on my needs and wants, diesel was the best choice.

I have been to multiple drag and pulling events including diesel power challenge, their were trucks running 10 sec qtr`s and them hooked to a pulling sled, also getting 20mpg in the economy event, if a gas eng is more powerful in a pickup size like you say, why are their no gas engines with 400/850??? and installed in a let say something everyone can purchase like a 3500 DRW , because most people with this truck are towing lots of weight and rather large 5ers, and the manufacturer engineers understand that a gas is out of the question towing heavy. A buddy at work runs a top alcohol rail car, it is give or take 750hp with out a blower I think in the high 500CI and it get torn down 3 times a year and it prob only has 50 passes that equates to 12 miles . another buddy at work has a 24v ppumped twinned 98 dodge that puts down 900HP and he has never had it torn down and will run the 1/4 in low 11`s plus he drives it everyday to work. 900hp gas is not a daily driver
