The engines are the same, and they all make the same amount of power. They just don’t look like that on paper. I can dig up references for this tomorrow if you like.

There was quite a bit of discussion about this back in 2010 when the new engines were released. It started in the thread with Mike Harrison, the chief engineer for the 6.2 L engine. He explained the engines aren’t actually detuned, but are rated differently because of the different emissions standards for the cab/chassis trucks.

I remember this thread well, we all learned a tremendous amount from Mr. Harrison. My old username was Crazy001 before it changed a few years ago, which is why the disjointed quotes. At the time I owned a 2008 6.4L F250… I miss that truck sometimes.

I can't speak to the tune, but physically the engines are the same. Without lowering redline, you can't really reduce power much with a tune and still maintain proper A/F ratio. So if they aren't 362/457, they should be very close.

Nice pics. Is it me or does that engine look really simple in design. Not like all the complicated systems in today’s engines. Maybe it’s misleading since it isn’t installed in a truck, but it looks like a motor from 20 years ago. I envision a ton of open space on the engine bay.

old guy here..
a "dyno mule" is an engine name for early production testing.. factory running a few engines for hundreds of hours on dyno's.
I have been in the industry for 50 years...
next step.. install it in a current production body.. for real ground testing...
OR
its a display engine.. no internal parts.. just a crankshaft
dude.
the official name is Development mule, shorted to dyno Mule
