7.3 chassis
Does anyone know how much if any physical differences there are between
the 7.3 in a 350 chassis and a pickup.
this would be in a 2023. I may need to replace a truck here in the near future

Are you asking if there are any differences between the frames from 2022 to 2023, or are you asking about differences between the pickup frame and cab-chassis frame in 2023? 2023 pickup frames are indicated to have some changes around the hitches for increased towing capacities, but I don't know if that is for diesel only. Pickup frames and cab-chassis frames are entirely different from the cab back.

C&C frame is flat from the cab to the back end, and narrower, for mounting flat beds and other flat frame beds, pickup frames are not that way.
Now, if you are asking just about 7.3 engine differences, to my knowledge there is no difference.

The C&C 7.3L is physically identical to the pickup 7.3L. However the C&C is electronically limited to a lower RPM. My C&C doesnt rev past 4200rpm and will shift at wide open throttle between 4000 and 4100rpm. You get all the torque, just not all the HP in the C&C.

No the engine differences. I know about the frame as I run reading utility boxes and need the chassis frame
and 60” cta measurements.

So if I would get someone good on a computer that knew what they were doing such as 5star? Tuning I
could unlock it and have a normal pickup engine?

I would imagine so? Take one for a ride though, you may find its unnecessary. My 7.3L is in an F550 that I regularly gross above 35K and it has plenty of power.

Not sure what you mean by "normal pickup engine" There is no difference in the engines, only the tune, revving and additional 1000 rpm is useless if the chassis combination isn't set up for it. I have headers, dual exhaust, speed limiter raised, and would have no need for extra rpm. With the C&C 4.88 gears, the transmission shifts so fast the engine is always in the torque band, and at 100mph a 10K # truck is scary fast (Just had to try it once on a straight flat road)

I had a 12 valve Cummins and it would keep up or maybe even out run my chassis 6.7 powerstroke. Now it was not stock but still I was a little dissatisfied at how much the 6.7 was detuned.
So I was wondering how much detuned and what the differences are in a 7.3. Are the pistons and rods different? Is the cam different? If I raise the rpm will it fly apart because the rods and crank are heavier and balanced differently.
