Why hasn't anyone released a HD truck with a Turbo V8?

Those engines were some real turds and I doubt that the head gaskets would live a long life with those power levels.

Funny being that they were regarded by many to be one of the most reliable engines of all time.

FORD 4.9L (300 CI) STRAIGHT 6

Top 10 Engines of All Time (#4): Ford 300 I6

How many did you have issues with that were personally your own? Did you ever blow head gaskets?

Sounds like an updated version of the Ford Barra motor would be what you're asking for. Ticks nearly all the boxes, but this motor won't ever be produced for the US (and pretty soon ever since they're shuttering the plant in October). It's an Aussie specific motor for their utes and falcon range vehicles. Here is the Wikipedia link for more reading.

I actually rode in a Falcon with one of those engines. Pretty quick. Not Corvette or Mustang quick, but pretty quick. I would actually want a bigger just like the old 300 was. The old 300 was not a high revver like those engines. Less horsepower and more torque down low.

Why the EcoBoost, from my reading, has an engine oil squirt to the
bottom of the pistons to aid in rejecting heat from the pistons

The Ford 6.2 has oil cooling for the piston also. Just like the EcoBoost.

OK, a Gas tow engine...

a straight 8, Aluminum, with a locking ring. *like used on E-locker* between the first 4 and the second 4 cylinders.
supercharged, injected. ceramic coated cylinders. and Variable compression.

all accessories are electric driven...or driven off the flywheel.

8 going up hills and 4 the rest of the time, or when needed.

note the front 4 would stop moving when not needed.

unlike other cylinder killing setups.

There is still lots of room for improvement in current IC engines and with hybrids, there is always the question which IC engine do you use with the hybrid system. Even with plug in hybrids, once you get past the first 50 miles not towing (probably not more than 10 miles towing any kind of load), all the energy used is coming from the vehicle's fuel tank so IC engine efficiency is still a huge factor.

What would you expect to tow with that hybrid?

Anything and more than the current gas or diesel capability.

Electric side would not need the 700+ horsepower of a Tesla but still to accelerate or climb a hill with electric boost would be effortless. Down the hill would put the energy back into the battery instead of blown off with the exhaust brake.

Sure you would still burn a lot of fuel towing. Not towing should get 50 miles range on electric with no trouble and 60+ MPGe for the daily commute.

I honestly think the combination of power, efficiency and emissions is up against a wall for improvement with the current options. Would be interesting if the urea tank could go away if this reduced emissions enough.

Yea I know I could not afford one either :(

I had one of those in my 95 F150. Slow as dirt, especially behind a 5 speed manual, but it was fun to drive. I had tons of transmission problems (they used a Mazda light duty trans that wasn't meant to handle the weight of the 150), but the engine just kept going. I miss that truck... =(
