Just finished swapping a 2001 5.9 in my '68. Eventually, I will put in a 46rh, but for now I'm running a 727. I used a Dodge Ram 2500, 5 speed OBDII computer from Solo PCM's in Florida. They zero'd out the VIN and milage. I used an SCT Tuner purchased from Scott a.k.a. Hemi Fever.
The long block was out of a 90k mile Durango that had a small fuel fire from a leak at the rear injector crossover hose. I washed the exteriorior of the motor, resealed everything, bead blasted, gasket matched and modified the inside of the stock intake, gasket matched the heads, threw in a fresh set of rod bearings, a new true roller timing chain and a Hughes Engines spec'd cam and springs, Hughes pluenum kit, a set of Mopar Performance valve covers and a milodon oil pan and pick up and finally I painted it and the accessories. I never had the heads off.
With a 3.23 suregrip, it will smoke them off with ease and chirps the tires hard into second gear. It's probably a high 13 second car as is.
The wiring harness was from Hotwire Auto, but it was not without some minor issues.
Exhaust was house brand from Summit including headers and full dual exhaust. Fit and quality were excellent requiring only minor massaging. I did strip and repaint the headers with VHT paint.
For the fuel system, I used the stock tank with 3/8 feed and return, a low pressure electric fuel pump pushing fuel to a surge tank mounted up front. It runs excellent even with only a couple gallons in the tank. Way better than a sumped or baffeled in tank system, as any bubbles are expelled before the high pressure pump can ingest them and feed them to the injectors.
Overall, it was a bit of a pain, because I had to learn all about EFI and the sensors, decidwhich way to go with the fuel system, and overcome the normal incidentals associated with this type of a swap, but it's soooo worth it now that its done.
As far as the power steering, it bolted right up to my factory ps box. I used a narrower battery and cut my battery tray to clear the pump instead of using the van PS pump and having to mess with the serpentine set-up from a van. I used the stock Durango set-up.
