Repair-It

I have to find one of the videos with the chief engineer talking about how they came around to this design. It is hilarious and ridiculous at the same time. Almost 100% of what he said completely validates everything GM has been doing with the LS for 22 years. 22!!!

That said it took a while for the LS to prove itself across the industry, especially in the aftermarket. So Ford should get no benefit of the doubt - it takes time after the new engine holds up to criticism and scrutiny as the LS platform has.

Anyway, the specs are class leading.

As an option in its 2020 F-250 and F-350 trucks, Ford's new 7.3-liter V-8—that's the largest displacement in the class—will crank out 430 hp at 5,500 rpm and 475 lb-ft at 4,000 rpm. That shades GM's 6.6-liter V-8 by 29 hp and 11 lb-ft and Ram's 6.4-liter Hemi by 20 hp and 46 lb-ft. Note that the 7.3 replaces the 288-hp/424-lb-ft 6.8-liter V-10, while Ford's SOHC 6.2-liter V-8 still serves as the base engine in the F-250 and F-350, producing 385 hp at 5,750 rpm and 430 lb-ft of torque at 3,800 rpm. The 7.3-liter will be standard on the 2021 F-550, F-600, F-650 and F-750 Medium Duty trucks and E-Series, as well as F-53 and F-59 stripped chassis, and in many of these applications rated at 8,500-plus pounds gross vehicle weight, engines are rated for continuous power and the useful rev range is much lower. In most of these applications, the engine is rated at 468 lb-ft at 3,900 rpm, with horsepower limited across the rev range to the 350 hp it makes at the torque peak.

Wouldn't be surprised to see this end up in all kinds of Ford-based engine swaps with a big turbo. What a novel idea that would be, eh? I mean, Ford guys probably cry every time someone (correctly) points out that an LS turbo is the fastest and cheapest way to run a Fox or SN95 Mustang down the track...it probably will still be the cheapest but at least the new 7.3L is basically a Ford LS. Their last pushrod V8 was the 302. And that was pretty damn old at the end. And never really made more than 225hp except in especially rare Cobra trims. And the blocks are weak as hell...351 and 460 were lame at the end, too (like 1996 or so)...but I digress. I welcome the competition.

Also, many of the Hemis seem like junk...so there's that.

By the way, the reason a 7.3L has only 11 lb-ft over a 6.6L is because GM is using direct injection and is the only one to do so in this application.
