More than a few times after I joined truck groups on Facebook and had people wonder why I am changing out most of the drive train.
Anything with a computer or needs a computer needs to go. The NP246 transfer case controlled by the tccm (computer). The transmission 4l60e can’t even shift without a computer. The main computer that works with the three other computers deciding when to send fuel, when to shift and even when you need four wheel drive.
or 
Try using the second one when the power goes out.
Nope give me a carburetor I can tune. 4 wheel drive when I want it. And an automatic manual shift transmission that I can shift up or down when I need to.
So I found me an older donor truck with a 700r4 transmission. NP241 transfer case. Now I could even use the tbi off that because edelbrock makes an intake for that. but no I needed a carb. Truth is I have two here already. Oh and I would have to switch to hei ignition.
So what next. I do a ton of research on the internet. I find I am not the only one. Many have changed to similar combos. Many have chosen to switch to carb.
So what comes first.
The engine. Disassemble all the wiring take off the ac, alternator, power steering pump. Disconnect the exhaust system remove.
Pull the engine out put it on the engine stand pull off the heads. Send them down for magnafluxing. and machine work .I need to check for the notorious cracked vortec heads. Disassemble the rest of the engine and send the block down for boring and magnafluxing. Oh yeah I need to buy pistons for that for the process.
Transmission 4l60e pull that. Pull the NP246 computer controlled constantly spinning transfer case off, and front drive shaft and rear drive shaft.
I will need to order a new hei distributor, put on a different gear for the roller cam.. On the front I need to do more research on the harmonic balancer. I wont be needing the seluctor WTF is that.
I will need to put a different flex plate and adapter to make up for .400 difference on the engine out put shaft. And maybe there is more. I will find out when I get there.
Its time to disassemble the k truck donor I didn’t buy it , just like the 55 I traded for it. Cab and core off so I can easily access everything. Oh yea did I mention I am disabled. Broken neck broken back some repaired some not. Living on a small pension. This will all be a challenge. I am relying heavily on utube videos to get me through.
I am not connected to the grid. I have solar not enough. And I have generators, so I can run power tools. I have a gas powered air compressor for air tools.
It will take me longer to get all this done but it’s the journey that is important. And I hope one day I will be driving Lucille as part of that journey.
