There's a 502 Ci motor that does. And I think it does so with a carb too. I don't know that it goes in a production vehicle though.
The Viper V10 was 2v and pushrod granted a 10 cylinder.
I forget what the last GM 8.1L V8 did - it was in the previous generation HD truck as the gas engine option but I bet it was close to 500 ft lbs. I know there are many an aftermarket cam setup that meks more than 500.
Since you didn't' specify any other attributes the LT4 is 650 or so lb-ft with 2V and pushrods. It does have VVT too. And a huffer.
I know you have a deep seeded hate for the pushrod engine but there are many that do make good power. Not saying there aren't 4v Dual OHC mills that don't make decent torque either. Part of why I switched to Ford from being a GM person is because of the ecoboost engine series. That and I hate what they did with my GM stock and the company needs to DIAF over the warranty lawsuits.
But I digress.

Powernation took a GM 632 and has it putting out 975 HP and 809 Lbft @ 5700 RPM. They did it on octane boosted pump gas. It is only a 2V pushrod iron block engine. I don't see how it MUST be DOHC 4V when a 2V can do it.

You can bank on some version of this motor making it into a Raptor.
There's already a ton of positive chatter / buzz about this new motor being a potential good platform for various racing applications.
Just may be the tipping point that will get me back into a Super Duty some day.
This is a big deal & is a great move by FoMoCo. I believe time will prove this out.

I would not likely be a buyer for a diesel, I do not start and drive that much, I could not justify that initial cost.
I could get by on the base gas engine, but likely upgrade to the top of the gas heap. It usually is just as fuel efficient empty as the extra torque gets you going smoothly with little difference in fuel usage to get the same amount of weight moving. Where it shines is on the times you really haul or tow something.
The diesel might be better but not at the extra initial an maintenance cost.
I'll go 7.3 GAS

I am hoping for 525 to 550 lb/ft of torque and at 21 to 23k tow rating. The current 6.2 gets up to an 18k rating with 4.30 gears.
