I hate to be dense but if the 4.7L works with the 100 series tranny and transfer in an 80, why wouldn't the 5.7L? I'm ignoring the tranny may not bolt to the 3UR.

Not the easiest thing to find a 100 donor, but any of the other donors with v8 has the transfer case outputs centered in the rear and wrong side on the front.
This truck was done with LC parts and a Tundra ECU with LC harness. That complicated matters, however you do not have to deal with chipped keys. It would be easier to deal with chipped keys than what we did on this one. You can bolt the 80 transfer case to the 100 tranny. So you need a 4.7 of some sorts, a 100 harness & Ecu with keys and a 100 tranny.
I know when I did the motor swap into my BMW I was able to buy a new chip for my engine brainbox - the exact chip most replace for a "performance chip" - that had coded key functions disabled since the motor, harness & brainbox I bought didn't come with the key (some do, so you can zip tie the key into the car somewhere)
IIRC the industry calls it EWS defeat/disable.
Just a FYI (more for the rest of us, I'm sure Christo knows/banged his head over EWS already) in case chips for boxes become a lot more $$$ viable option down the line instead of super specific harness & box combo once the bulk of the supply dries up.
Heck of a good timing on this, I haven't even popped my hood to further investigate my grey smoke of last week, I have a gut feeling I may be in line for something like this if I don't find a 1FZ I want to swap with nothing more than a HG tradeout.
Are you capable of making the a/c lines in house? I had difficulty finding someone that could crimp the odd sized hoses. I saw yours was not installed yet. Mine was also a bit tight around the p.s. lines, but fix that and also re-routed the brake line in front of the steering box.
How far forward is the transfer case?
did you cut any part of the tranny tunnel for the t-case?

Nice work Christo! Good to see your re-investing on the 80 once again. Too bad there is no adaptor to mate to the 80 transfer case or even the 80 manual transmission.
Seems very reliable and adds too much cost to the set up to replace it all. If a person is going to invest that much in the drive train it may make more sense to invest in a cheap chevy set up just because of the availability of the LS motors and afterrmarket alone. Maybe a core charge for the old 4.5l and setup for another market to reduce the cost?
Unfortunatly the link isnt working for me so can I stop by and take a test drive to maybe convince me to be a customer once again? Last time you let me take your cruiser for a spin I think it was the old bus before it was painted yellow when you just started up in your garage in lakewood i think it was to test your original suspension lift combo. Anyway my lift is still working great and good to see you invest your time before you release another product once again.
Hey Christo...how does this compare to a TRD supercharged truck?
By the way...it looks great.

The 200 transfercase front output is on the wrong side to match the 80 axle. I doubt also if the engine will fit inside the frame rails and shock towers.
I just installed the pass side tray on mine for a second battery. I had to move the PS res, but other than that its the same as adding a second tray anyway. Moving the washer bottle etc.Nice work Slee. How would this swap impact Dual battery set ups? the radiator is still 80 series?
This is a great idea. $10,000 is right in line for what you would have in a good Gen III/IV GM, Mark's adapter and all the related stuff.
