Questions on a project

So as far as the electronics go would there still be an issue in terms of communication if I were to get an ECM for a new production c13 and delete what's not needed from the file? For example the emissions since it's a pre-emissions engine, the setup for the mechanical fan since I'll be using at least three electric fans on the radiator along with a water to air intercooler and water to air oil and transmission coolers, and possibly the engine brake as well since I don't see there being a need for it in this application.

As for the frame since someone mentioned it earlier I think the body will have a tube main section that includes the engine mounts, the transmission crossmember, the passenger compartment, and then have the rear suspension set up bolt on as an independent unit for easy maintenance, and have the brackets for the lights be welded to the main structure, maybe for the headlights have buckets that accept units from a Pete 389 and set the buckets up so that they can be adjusted up and down by loosening a locking nut and then adjust it as necessary

 

My next thing I'm unsure of on this engine the fuel system, would it benefit from a lift pump, if so what gallon per hour rating, does it matter if it's electric or mechanical? Does it need a return line from the injection pump and the injectors? What size are the ports on the inlet for the engine side of fuel system and on the return side? Thanks in advance

 

Okay so I've hit a road block on this again, this time with the cooling system and the oiling system. Does anyone know what size are the radiator hoses are on the c13? Does anyone know what size the lines are for the oiling system in regards to the oil cooler? I think this Is a stupid one to ask but is the oil pump separate from the air compressor and will I have problems with the engine when I delete the air compressor? The way this is shaping up it's going to be dead weight because it's superfluous and so I figure I may as well get rid of it

 

I wasn't planning on removing the oil cooler, I was thinking of adding a secondary one if the primary one didn't perform as well, although given the engine's intended usage I don't think that'd be a problem. My next biggest thing since I'm figuring out the vooluny system

I wasn't thinking of removing the oil cooler, I was thinking of adding a secondary one if the primary didn't perform well enough although given the engine's intended usage in heavy industry I don't see that being and issue
