Ford 6.8 Liter being replaced

Recommended Posts

Attended a RV show in Chicago this weekend.  Talked with a REV/Fleetwood sales rep and he indicated Ford is discounting the 10 cylinder 6.8 gas engine, we did not discuss F53 chaise. Curious if anyone else has heard similar news and what will be replacement?

Yes, it has been well publicized that a brand new 7.3 liter V8 will replace the 6.8 liter V10 in HD applications including E350, E450 and F53 chassis.

There is a thread on another forum about the new V8, same old complaint, terrible gas mileage.

Yeah, you cannot make enough power with gasoline to move something as large and heavy as an RV and get decent MPG’s.

IMHO Ford messed up when they dropped the 460 engine. It was a workhorse.

This is basically the 460 re visited. With output of 350 or 430 horsepower at 5,500 rpm and torque of 475 ft.-lb. at 4,000 rpm depending on which web site you look at. It looks like a step backward to me.

A few months down the road for a reply but...Power and performance and mileage is not a concern for EPA, even though they push small turbo engines.

It  takes the same amount of power to do the same job regardless of the power plant, number of cylinders or turbos. Cutting compression, decreasing timing and enriching the fuel mixture, to aid Emissions controls takes away a lot of power  load capacity and decreases mileage a lot. This is one reason they now sell 7 and 8 gear transmission. Engine doesn't have the power multiply what is available, in the now narrower power band. Our3800 lb  AMG 6.3 Renntech tuned gets in 7th gear up hill, on the  flat, anywhere gets 22-24mpg, at 75 80 100 mph as long as you don't hit the throttle wit approaching 3 times the power of the Ford. Our Ford Edge St 2.7 twin turbo .345 peak hp on 93 octane might get 25mpg on a long stretch, and engine stops at lights, hauling 4500 lbs, has no engine breaking on hills and constantly shifting in hilly terrain.

If they Built a 7.3 liter/440cci engine right with 11to 1 compression, requiring 93 octane, aluminum engine direct injection,  broad power band cams etc it would still not get 20 mpg hauling a heavy pickup or Motorhome but would do far better than  low compression campfire. however  550-600 lbs of torque or more if built right and 450-650 hp hp or more would move the vehicle like it should. Enough money i can give you a thousand and more hp and  up to 1100 lb ft of torque  but in no wise can i or anyone else cheat physics and give you 25mpg hauling 6,000 to 25,000 lbs, or anything similar as the EPA is  trying foist  on Americans.  250 hp and twenty sped gear boxes can give you a good but slow tractor. and on the flat land, of Indiana, you can even get up some speed with the wind at your back.
