Ford 7.3L Gas Engine

[Tractorable]

Specs were just released on Fords new 7.3L gas motor, 430hp and 475lb/ft of torque. Cam in block push rod motor, forged crank, pistons/rods ready for boost, 4 bolt main bearing caps, cast iron block, built for durability, longevity, simplicity, and ease of maintenance. Makes 400lb/ft of torque at 1500rpm and will be mated to a beefed up 10 speed auto trans.

I like it, more power for towing than the 6.2L, and should last forever and be cheap and easy to maintain. I bet it’ll make a heck of a drag motor with a supercharger or a couple hair dryers bolted on.

Interesting. I sure wish when they do these interviews they would step away from the background noise. That said, I think it is smart of Ford to redo the big gas engine. :thumbsup:

I think it’s rated at 4000 rpm not 1500 but the 400 foot pounds seems believable.

I think the old GM 8100 (8.1L) was 330hp at 4200rpm and 450ftlbs at 3200rpm. It was a real torquer but drank fuel.

I have serious doubts about the new 7.3 gasser being any better. Big displacement high output gasser and good mileage doesn’t go together. The 8.1 hasn’t been produced in 10 years but I’d still think that over a Ford anything. I hope the scraped the duel timing chains and plug spitting problems.

I don't know why people make a big deal about the plug spitting problem I have 2 v 10s and have only lost 2 plugs at a cost of 75$ a piece to replace. The motors have 425,000 and 497,000 and still going strong daily driver. No other engine repair done to them !:cool2: Best gas engine since the 460....:drink:

Wonder what the gas mileage will be with it? I'm guessing maybe 15 hwy, 10 towing? If you gonna work the horses you got to feed them.

Maybe in a 250. I’m guessing the medium duty truck is closer to 5 mpg loaded. I’d be surprised of it got 10 towing a big load in any truck.
