I'm going to guess that if they can get this engine past 150K miles without the exhaust manifold bolts breaking off.......it will be a winner.

Looks like that new 7.3L gas engine will be seeing school bus duty.


People who count on their fingers should maintain a discreet silence.

If Ford doesn't kill off the Econoline cutaway chassis, I can see that. The Transit is making a slow entry into the school bus market.

I can see lots of paratransit vans using these as well.

Glad to see the V8 making its return to the Raptor. Dodge is also rumored to have a 426 coming out. Something about big block V8s...enjoy them while they last. Really loving the 6.2 supercharged Hemi with the A8 transmission. Take care all.

Doubt it...the Transit already has its own line of engines.

I have a friend that works at KTP - Ford plant as a product development engineer in Louisville and he showed me this engine a few months back. Kind of interesting how they camo and hide everything even in the plant. He is really bragging this motor up saying it is much better than the old gasser it is replacing. Surprised me how much back pressure this engine produce on our exhaust system. Clamp of old exhaust was not strong enough and broke loose. They measured over 1,500 lbs of back pressure on the exhaust system.

There's something to be said for the simplicity and reliability of pushrod mills. GM's success with the LSx family, and its compact nature, as well as Mopar's HEMI have proven it isn't obsolete yet. I couldn't imagine trying to turn a wrench on a comparable displacement OHC mill in my Jeep crzy


My understanding is OHC is more advantageous in high revving engines . Typically , diesel engines are lower revving , where push rod system is fine .

This is great something modern with some big grunt that gets around all the diesel complexity and bolt on windmills.

A modern big pushrod mill with variable timing and a high BSFC sounds like a killer package.

Mated to a wide 10 speed it could get decent mileage.

Thanks, I missed that detail.

Why not just buy a diesel if you require this much towing capability?

My notoriously hated 05 PSD with the 6.0 averaged 15-16-mpg loaded to the gills hauling a 3 horse trailer with living quarters, 3 fat mares, tons of excess junk and other items when we moved from WV to Florida, over 975 miles.


When my dad bought his 2002 Silverado 2500HD, he chose the 8.1L gas engine. I asked him the same question - why not buy the diesel? He said that option was close to $7k at the time. He can buy a LOT of gas for $7k, and not have to deal with DEF fluid and DPFs and all that BS.
