Ok.  I'm 14 and I have this classic chevy.  I wanted to make the Blazer into a daily driver but still be able to go wheeling on the weekends.  I'm posting pictures of it below.  With the tight budget i'm on, what upgrades do you think I should put on.  I was thinking about a 3" body lift with some 35's, but i don't know too much yet and i was wondering what you all might suggest.  Thanks for your time.  

Hey, my name is charles, and i have a 1984.  What i would do is add a 4" suspension lift and run 35" tires. my website for my truck so you can see what i have done to mine is "http://www.cardomain.com/ride/699870"  I have 11" lift and 35" tires now, but soon to be 48" TSL/SX super swampers.  let me know if i can help you out with anything  

Chevy made a 2wd blazer in that era as well as a 4wd. I could not tell which one you have from your pics. If it is a 2wd you will run into trouble pursing your plans

6 bolt lug pattern, and a hub sticking out of the front wheel............it is definitely a 4-wheel drive. Lots of potential....lots.  

definetly go with the suspension lift instead of the body you will be happier in the long run  

i deffinately agree body lifts are like soo fake as apposed to suspension lift  evertone has body lifts at our school and they dont look as good as a suspension lift  

K5 ! Full-time 4X4 ! Just like mine, but I got a '77. Definately a cool truck! This is a great base from which to build, A lot of potential here. Find out what ya got as far as axles, transfer case, & tranny. Probably the basics - Dana 44 front axle (3.07) and GM 12-bolt rear axle. (3.08). As far as the Transfer case, there should be an ID plate on the front of it toward the passenger side ( probably a New Process 203, or 205) The 205 is a much better transfer case. Tranny is either a TH400, or TH350 depending on the engine you got in it. If you look at the Transmission pan underneath the TH350 is basically somewhat rectangular with one corner cut off, The TH400 has two flat sides, one side is sorta pointed and the other has a square projection. You may also have a TH700R4 tranny in there - the pan is square on theses. The best in my opinion is the 400, followed by the 350, and the TH700R4 is the weakest - there are transmission kits available to build it up tough though. The Engine can be identified by the truck's VIN number stamped just inside the windshield on the dash, or on the vehicle emmisions decal on the bracket above the radiator under the hood. The rear axle can be identified by the number of bolts on the rear diff cover, either 14, 12, or 10 - best to worst in that order, again in my opinion. The front axle, if it's a Dana, will have a Model Number stamped on it on the front lower right hand corner of the case looking at it from the front of the truck. You'll probably have to scrape off years of mud & dirt to read it, but it should read "44" There are also two numbers lightly stamped on the front of the axle to the right (driver side front) don't scratch too hard on these or you may just scratch 'em off and not be able to read 'em. Use an abbrasive sucrubbing pad like a dishwashing pad.

This should get you started. Sorry about all the info, but you asked! 

As far as the lift, I'd forget the body lift kit, I think they look terrible too, and go with lift springs front & rear. You can put lift block in the back as a cheap lift, but if you plan to go off-road or muddin you will have problems with axle wrap. Lift springs are the safest ant toughest way to go. Whatever you do don't double up add-a-leaf springs, or install lift blocks in the front!! Both of those can be very dangerous. If you decide on block for the rear, don't buy the cheap aluminum ones from the local auto part. Those will crack on you, and it could become expensive. Get the cast Iron ones.

Let me know if you need any more info on your 'Beast'. I can tell you all the F**ck ups I made, so you won't have to, and spend a whole lot of money learning the hard way, like I did.

As far as exhaust, you will probably want to scrap the Cats (catalitic converters) - I don't think the 73's came with 'em, and you shouldn't have a problem with the law if they weren't factory installed. I'd look at Dynateck Bullets if you want glass-packs (loud), or Flowmaster super 40's for dual mufflers - they have a deep aggressive growl. I like the 40's myself. True dual exhaust, of course wth a cross-over pipe behing the transfer case.

That should get you started! Be sure to post more pics after you build up your Beast. Best of luck!

btw- Order a catalog from LMC Truck at 1-800-562-8782 or on line at http://lmctruck.com They have the biggest supply of restoration parts for your Chevy truck.

by the look on your pictures your motor should be a 350 (as indicated by the grill unless somebody swapped in another one).  The transmission should be a th350 as the blazer is not a big towing truck and would probably be like a 1/2 ton.  should be a d44 from and 12 bolt rear.  by the look of the hubs you have the fulltime np203 (np 205 usually came with the factory warn locking hubs)

Thanks so much for the info guys, it will helps alot.  I have talked to a few people around town and you were right, a suspension lift is the way to go.  As soon as I get anything done, I'll post pictures.
