Actually it would be fairly straight forward as long as the speedo runs off the ring gear tone wheel....The 24V ISB is a pretty straight forward engine. Power the lift pump and ECM and your pretty much ready to flash it up....Too bad the VP44 fuel pump is such an expensive piece of ****...I'm about due for a Cummins ISB, ISC or ISL recon swap, been 8 months since I've done one at work. I'd go 12V with a worked P7100 pump, nice sound and cheaper to tweek.
