Re: 8.1L and 4L85e swap into a 1972 Custom Camper 4WD
A lot has happened since our last post on this truck project. The good news is that the 72 K20 Custom Camper is done. The 2004 8.1L was completely rebuilt and a mid-range Competition Cam installed. I had it dyno-ed in Seattle. 450HP at the rear wheels and over 600 ft/lbs.
Just a quick review. I started the swap in 2014 after acquiring the engine, transmission, ECU and a variety of other parts from a 2004 Suburban. I determined the basic architecture of the new setup - mounts, crossmembers, firewall mods, etc. However, I quickly figured out that I was over my head when I tackled the wiring (New harnesses throughout, new Vintage Air A/C, moved gas tank.) So I shipped it to my son. He is a detail wizard. Thanks to him, the finished product looks, runs and drives like GM did it. In particular, the steering box made a huge difference. It has won a couple of trophies in the Seattle area and now resides here in Wasilla, Alaska where it is lurking in my garage, waiting for clean dry streets.
