it is not really what i would run thru it as it how different things are controlled, electrically protected and such. i have plenty of ideas for future things but it is very complicated to explain what my plans are. perhaps some specific question you might have on something.

This is a build thread after all...so I'll take a brief departure from trip photos to show some recent updates to the Tahoe

After swamping the truck in a mud hole in Maine, just about every breather tube took on mud & water. The most vital for me to change out was the transmission fluid. I've been wanting a serviceable pan for quite some time, so I found one with the deep dish option. To properly service the transmission, I had a shop hook their machine up to the aux tranny lines and flush the system using Dex VI fluid and NO CLEANING agent. After 1k miles+, tranny runs like it always had...no problems!

The rock sliders were rusting on the tops (from stepping on) them and numerous rock strikes (bottom). I used a simple rattle can of black and it came out pretty good. But I need a better solution b/c the paint hasn't lasted long and I really don't have a lot of interest in repainting them every few months

I also installed this massive 12k GVWR radiator (AC Delco) that was originally intended for the 7.4L K3500. I ended up having to fabricate new top mounting brackets and purchase the upper/lower shroud to clear the taller radiator. Otherwise all the cooler mounts were identical and it was fairly plug & play.

Hey Sunlit, here you go!

ACDELCO Part # 21371

The kick in the butt is that the shrouds are discontinued and so is one of the top mounting brackets. The 454 K3500's are tough to find in my neck of the woods...so it took some digging to find a new shroud (Chevy warehouse in PA) and had to fab the metal brackets vs a Pick-n-Pull.
