Can blazer body be put on Tahoe chassie. What parts can i use. I have the complete Tahoe.
 
Engine,transmission with wiring harness for both,pcm,air filter hosing,over flow.

Those I know for sure. Harness will need reworked.

Others will chime in it's the weekend little slow.

Brake booster, steering collum. What bout blazer body mount to Tahoe chassie?
 
If engine and trans. Go into blazer. Tahoe has automatic 4x4. How will I go about it being put into blazer?
 
Doubt brake booster,steering column and body mounts will work.

Is your truck a manual now?

Lots of guys here have done the swap both auto and manual. Just got to read up on it.
 
Zoomad and sreidmx both have current post in build section on the swaps.

Both automatic
 
Tahoe has 116" wheelbase. K5 has 106.5" wheelbase. Don't think the rear axle could be relocated that far, so the body swap would take a lot of changes. Plus, most guys wheeling those do a solid front axle swap. So yeah, drivetrain swap into K5 makes more sense. If you don't mind being 1/2-ton, the rear axle with disc brakes is kind of nice, but the gears are likely different than your front solid axle, so maybe just the brakes can be swapped over.

If the transfer case in the K5 is good, I would keep it. There are a bunch of reasons not to use the NP246 case in the K5:
  • It's driver's side drop, so you would have to swap your front axle for a Ford or something. (or swap to IFS!)
  • The front output is a weird reverse slip yoke, so you can't get much front axle travel, even after you adapt the Tahoe shaft to the right length. I suspect it would work crummy with the added driveshaft angle of a solid axle truck. Plus, no C/V joint. Remember, the diff doesn't travel in an IFS truck.
  • Auto shifting is a pain to adapt. I understand it can be swapped into other vehicles, as it uses a stand-alone control module. So you would need the control buttons, the TCCM and probably the front actuator. With the SFA, there is no use for this front actuator, but without it hooked up your control panel will blink at you all the time. It might still shift, though. You could hide the actuator. You probably can't just fake it out with load resistors or steal just the "smarts" out of it because it moves and reports back the resulting position. I think using "auto" mode is next to impossible.
  • That clutch will fail eventually, you need to use special GM blue fluid, the actuator will eventually fail, etc. All unneeded hassle when floor shift is more reliable.
  • It would be better to convert the case to manual shifting. Possibly the selector shaft from an NP208 or other manual case can be swapped into the NP246 to allow this. The actuation is similar, the automatic part is just from an electric motor mounted to the outside of the case. PLUS, what would you do with the floor shifter if it was auto shift and where would you mount those control buttons that didn't look hack? (although swapping the whole interior from the Tahoe to the K5 is an interesting idea....) So why not just start with a manual transfer case to begin with?
 
Ok thanks for all the helpful info. Think I will put engine and keep my 208 . Making it an easier swap
 
Seats. The 00-07 seats with built in belts is becoming a popular swap, front seats then the 3rd row (if the Tahoe is equipped) fits in place of the Blazer bench.
 
You can take any or all and swap with, how much work you want to make for yourself is the question.

Seats, front easy swap. Brace the floor top and bottom, good to go. Rear seat, again as noted above the 3rd row fit with a little more fabrication but looks slick. Plus you can fold each side down or out separately. Look up Merrick's garage on YouTube for a pretty good video on what to do there.

Engine, again becoming more common, been done hundreds of times. Search and you'll find them all here. Including mine. Trans will come with, just bolt your 208 or find a 241 from a later squarebody, 91 if you need the cash output for your stock 5.3 harness. Speaking of harness, it will need to be reworked, but again many have done this lots of details on here and other sites.

I personally wouldn't go through the bs to swap in the Tahoe dash to the blazer.

The rear axle is good part, but you will have to cut off the coil spring suspension brackets and burn in leaf spring perches and shock mounts.
 
Sure, anything can be done but just to clarify there is very little to no parts that are directly interchangeable, meaning there is no bolt in and go. Swapping the '74 body over would most likely take extensive fabrication to make look reasonably good and not like a hack job and for everything to work, but that would give you the old '74 looks with all the modern driveability improvements of the newer machine. The 5.3L engine swaps are getting popular as they are decent running but do required a good bit of electrical and fuel system work to make them work in the old '74. Same thing with the trans as it would improve the driving of the truck but also requires a speed signal. Not sure how to do that with the NP208.
 
I would't intentionally swap a np208 into anything but a trash can...Satan's slip yoke can burn in hell

Typically you get the adaptor and reluctor ring that allows you to use a speed signal. Advance Adaptors makes one. And check out the engine before you get going-rolled trucks have a bad habit of engines failing if they were ran upside down and starved for oil.

Forget trying to make the frame swap work-too much effort for two little gain. The best bet is the modern drivetrain and maybe the seats.
