Detroit 12v92 swap project

Hi all, I'm planning out a project a factory two-axle Peterbilt 379, I'm going to be dropping in a 12v92t Detroit that came out of a fire truck according to the website, I'm going to put behind it an Eaton RTLO-22918B since I'm unsure if the factory 10 speed can handle the power. What bellhousing will I need? What clutch kit will I need? Looking at the listing for the Pete it indicates the Cummins in it is rated at 1,400 lb-ft, about 600~700 below the Detroit, would I want to swap differentials to one that will handle the power? Will the tach pickup for the NTC Cummins work with 12v92? I have a feeling I'll want to add a boost gauge and an EGT gauge, should I try and make the factory speedometer work or should I get a GPS sender? Will the factory air cleaners supply enough air for the engine? If not, will the factory mounts work with aftermarket ones that would flown enough air? Would it be worth the effort to plumb in a CO2 connection to shut it down in case of a runaway condition? Thanks in advance for the help.

 

It's going to be a toy, I don't like to associate it with show trucks because I'm not a fan of show trucks as I feel like they lose the essence of what a truck should be, a work horse first and then a show piece. It's not going to be a work truck because I'd have a Volvo VNX for that, plus the Pete at some point had the fifth wheel assembly removed so I figure it'd make an interesting candidate for some wrenching

 

Okay, as far as the hood goes would it be better to go with an aftermarket fiberglass one for the 127 BBC or should I try to find an original aluminum one? Where does the tach get the sender from, transmission shaft? Alternator reading? What?

 

Looking at the electrical side of this, is the system nominally run on 24 volts or just the starter circuit? What output is the alternator rated at?

 

What goes into a 12 volt conversion? As for remounting the cab I imagine the hardest part would be the weight as it does not seem light, how much would I be dealing with?
