If it were my truck it'd get a mild IH DT360, or attempt to stuff a 466 in it.
Way way too much work if you ask me none of the engines listed are worth swapping for
If you must, just do a cummins swap.
The 3116, 3126 and c-7 are all just a line of variations of the same engine. Just newer successions in the same line of engine as they evolved to meet emissions.
All those engines are like the 6.0 powerstoke of cats engine line.
As much as I like cat, there isn't one I would recommend to put in the time to swap. Maybe a c6.6 and they are not a power house and still have problems.
Doing a mechanical injection swap on a c-7 would be the equivalent to p-pumping a 6.0. Totally not worth it and would cost a small fortune.
In all reality I would consider an older dt466 before I would put a cat in.
Btw I worked for cat for 8 years building engines. Just my experiences.
Personally i just am not impressed with 3126/c7 3116 ect ect engines
and fwiw not all c7s are perkins engines
I work for a cat dealer fwiw
Dt360 a great engine that's billetproof and makes good torque

The 6.6 is a Perkins. The 3126,3126, c-7 were cat. 7.1 common rail is a cat too I thought. I haven't been in the dealer world for a while so maybe they changed the 6.6 and just call the Perkins a c-7 now?
But yes dt360, 436 or 466 will work. Still unique. Just a lot cheaper, easier to work on and buy parts for.

What's your budget?
How much work does it take to put 650++ hp out of a DT360?
I'm not starting a pissing match I just cant believe that the c7s etc have that bad of a rep. Hell at the ford dealership we love working on the cats and very rarely seen them come in for any thing other than services and small oil leaks. Hell my girl friends dad has a freightliner box truck with a c7 with almost 500,000 and just put it first set of injectors in it.

What would you recommend?
I guess we just saw a lot more of them being at the dealership. I've worked on a lot of them at our shop outside the dealership too.
I mean the 3116 is a mechanical unit injector with a rack that uses dial indicators on each injector to set it when replaced.
The 3126- c7 were heui injection soo not the best in a heavy duty environment.
And the newer commonrail stuff has proven to been even less reliable.
Cat made a lot of much better engines than their mid size 7 liter engines. Just not worth it in my experiences. And they DO NOT hold up well at 300hp +
Where did you work?
