Engine swap questions

I understand, and value the information. I am weighing my options, to see what’s best for this. The ISM in it is rated for 425 right now, which is more than enough. I don’t need 800hp to the tire. I run a C11 daily as-is (and it’s got its own issues), but it outpulls all my friends trucks (mostly ISX KWs) while being rated under 400hp. Maybe I should stick with the Cummins, I just like CAT motors better.

Oh well, I’m only out the 2k for the girl and 6k for the new frame rails and installation. That’s why I came here, to see and learn. I appreciate all the guidance, and until it looks bleak as heck, I’m still down to give it a shot.

 

yeah, “Peterbilt” almost always harkens images of 359/379/389 trucks. I’m a bit of a cabover freak. Always liked them back in the day. Had an argosy for a good while but it was retired couple years back. Parts were nonexistent after they became export only, even though theyre made here.....

This Peterbilt model and the 520, seem to really be hated by dealerships. Which might have been more understandable to me if it were a normal cabover, but they actually laid it out pretty well. My lameduck skills don’t have much trouble messing around with it as-is, and I feel like it’s easier to work on than a true COE style arrangement. Pulling the engine and doing anything like that is easy like a normal 379.

As for the gauges, I can pull them out and run standalones, I can make custom intake and exhaust plumbing, and the allison should bolt up and function after some Iscaan and cat ET tinkering. I originally thought this had a BCM and a bunch of stuff like the argosy, but I’m thinking it doesn’t based off what I believe to understand from Pushbroom’s posts.

Which means the only things I need to worry about are the in-cab electronic controls....of which I think only 3 interface with the engine directly. TPS or whatever, the jake controls, and the manual fan switch. The rest should be either simple chassis wiring, air lines, or vacuum operated (wipers, lights, difflock, etc).

Pushbroom, does any of that sound accurate?
