So I just bought a 1983 k5 blazer ... Idk everything about it but I'm decent with a wrench ... I want to make this thing a beast and some of the work is already there ... So here is what it has to the best of my knowledge

37 x12.5in Goodyear wrangler mt (with spare )
About a 6 inch lift ( not sure how to tell)
Th350 that was broke (being rebuilt currently )
4wd
Grill with lights
Front tow hooks
Exhaust system had leak so I'm replacing (should I do single or dual exhaust ?)
Removed all carpet and will be linex or possibly monstalined
350 v8

Any big recommendations with price estimates on what comes next

Here's my list so far
-rebiuld transmission ( got a family member doing it for part cost only )
- exhaust system 200 -400
-linex 800 / monstaliner 250

What else ? Thanks in advance
 
I'd stay single exhaust if your factory manifolds and y-pipe are still intact. Save dual for when you go to headers.

At 6" and 37s, there are some equipment and details (besides just a lift kit) needed to make it safe and reliable. Extended brake lines, CV driveshaft, drive angle correction, steering geometry correction, steering box bracing (bolted and/or welded), gear changes and/or axle swaps to compensate for the larger/heavier tires, etc.

If the truck was built right, some of this may already have been done. If not, I'd prioritize it over any cosmetic upgrades or creature comforts. The truck will run with a lift slapped under it. It just won't run very well, and you will likely spend a lot of time fixing it. It's worth it to spend some time researching the parts it already has and go from there.

Do you know what axles it has and what gear ratio is in them? What transfer case it has?
 
Rebuilding a TH350 should be cheap, like $6-800 (in the DFW area, at least). As RG said above, stick with 3" single exhaust - no need to go duals.

Check the steering & front end components for any slop, and replace parts as needed. Figure out how to get the front rotors off and grease the wheel bearings really good - you don't want one failing away from home.

What's your axle gear ratio?
How many lugs does each wheel have? 6, or 8?
 
You can check it very roughly by jacking up the rear end and spinning the drive shaft and counting the number of rotations it takes for the tires to make one rotation.

But I agree with blazinzuk. It's better to go ahead and change the oil in the diffs. While you're in there, spin the ring gear until you can see all the info stamped on the edge of it. Usually at the end of the stamping will be two numbers. One is the number of teeth on the pinion. The other is the number of teeth on the ring. Divide the big number by the little number = gear ratio. For my dana 60, the numbers are 41 and 9. 41/9 = 4.5555 or 4.56:1 gear ratio.

Agree, but not that one. Mine was $20 out of the local junk yard. Also, if you go this route, be sure the u-joints in the shaft are tight before you pull it. The junkyard I went to had 3 shafts available, but 2 had loose u-joints.

Agreed, but some folks would rather spend a few extra bucks not to have to hunt one down, pull it, clean it, torch the tabs, etc. That one is ready to go right out of the box and still way less than any Borgeson. :dunno: Builders choice.
