Guys,
I have some questions about a swap I'm engaged in at this moment; I'm taking a gas Vortec automatic K3500 and swapping in a 6V53 (two-cycle) Detroit Diesel and a straight-drive transmission. I'm good at the physical end of it, but the electronic end has me a little concerned. The truck has a lot of nice features that I want to retain, such as cruise, abs, to name a few. Also, I want all the stock gauges to work as they did before; I don't want to add aftermarket gauges, etc.,, I want the truck to look stock inside.
Why am I installing a Detroit two-cycle? I love the sound they make, and if you set them up right they're pretty economical. Other than that, it makes no sense whatsoever. By the way, the engine I'm installing is aluminum, so weight won't be as much of a factor as putting in an iron job would be.
I'm installing a 6V53 and a ZF 650 six-speed trans and a NP 261 (non-motorized) transfer case.
My questions are these:
1. Where does the tach signal come from? Will I need to rig up a drive to make the Detroit spin the Vortec's dizzy to get a tach signal?
2. Can I install a 'diesel' gauge cluster and have it work with the gas (Vortec) electronics?
3. From where does the front axle get its signal to engage when you put the truck in 4wd? The truck has a mechanical transfer case as it has a lever in the floor; no push buttons.
4. What will I have to do with the old transmission's range switches, selector switches, etc. to fool the computer into thinking the truck is in gear?
I realize these may be a lot of questions, but my knowledge of cars stops with HEI's and Quadrajet carburetors, so please keep the answers simple.
Thanks so much!
