I haven't posted much here, but I did a lot of searching/reading here that helped with this swap!

Painless wiring harness, Wheatly tuned, motor mount adapter plates from Ebay. Had to change the input gear in my transfer case (NP241) then it bolted right to my trans. All guages work except for oil pressure and tachometer. Cruise control and ABS don't work. I'd like to get the cruise working if possible. I might just ditch the ABS if it's too much work, it didn't work that great in the first place! Maybe some day I'll hook up the AC, for now I just drive fast with the windows down.

Nice truck get some new plug wire stock ones suck. I just bought some taylor 409 race wire from summit and they make a difference, my 5.3L runs so much smoother..

Truck looks good, want to come to Vegas and finish mine up? Thanks for your help with the TCC wire. I tested all the wires and I have it right, but my old trans just isn't working with the 6.0 so I am shopping for one that will. Hell, at least it runs, some reward anyways.

Good luck with finding a new 4l80e, have you been checking Ebay? How do your Hedman headers fit and do you have any pics?

truck looks beautiful :eek:

no AC anymore?

I didn't want to notch my frame, so I'm saving up for a compressor relocation kit! It's ok, doesn't get that hot here anyway!

Looks good. One question though, your steam port from the heads, is it tied into your line going to the water bottle?

very nice!

Redheartbeat: that is the line from my throttle body bybass. It has been working, is that not a good idea?

i guess it's okay if you don't need water in your engine. Eventually all the water will be in your overflow tank instead of in the engine, if you're actually getting water flow out the steam ports as you're supposed to.

Sweet. I love it

Where'd you get your input gear? Also did your original VSS in the 241 work or did you change that as well:hyper2::hyper2:

Yes, I used the original VSS in my NP241.

i simply stuck the TB bypass deal into the now extra port on the rad. its the one you currently have capped off. i went down to ace hardware and took a piece of the hose that once fit the rad (heater core hose) and got me a nylon reducer that fit the smaller tb hose.. works for me..

How did you set up the shifter? Did you use linkage or did you convert to cable? If you kept the linkage please post up a picture or something! I'm swapping in a Vortec 454 and 4L80-E into my 89 K-1500 and am stuck on this linkage stuff. I want it to look stock inside so a floor shifter is out of the question..... :(

nice truck bro. i really like how your exhaust kicks out

modular93fox: I fixed that a few months ago, here is what it looks like now

xXxSilveradoxXx: I used a floor shifter from Lokar (Lokar: Floor Mount Automatic Transmission Shifters) The stock linkage would have worked with some modifying, but I always wanted a floor shifter! Cable shifter might be easier for you and shift smoother (here is one example Lokar: Column Cable Shift Linkage)

small1town9kid: Thanks! I haven't been driving it much the last couple months due to the snow. I can't wait for this crap to melt and for Silver Lake to open!
