Second truck, first 4x4....using and abusing. PAINTED!

From a young age I've been into offroading. Normally as a passenger with my Dad, I've had so much fun. When I bought my first truck however, it was a new trouble free, good gas millage, lowered S10. I still have it, its my DD. I bought a quad 3 years later, '04. I still needed that 4x4 though and it had to be a K5. Finally had the money late last year to buy this.


1985 K5 Silverado, 350, 700r4, 3/4ton D44 and 14BFF. 16" Centerlines and newish offbrand 31"s.
My first used car purchase, which comes into play later. The picture is from my first time out with it. The shell it came with had old rack holes drilled all over it. Cut it up and threw it away after no one wanted it. Picked up the white one for $100. No holes and it had sliding windows.

I picked it up about 300 miles away. Bringing a friend with me and lots of tools, fluids, and money, I made the drive without any trailer available. Looked it over, talked with the guy, and drove it around by myself. The PO was waiting to pick up his daughter and had time on his hands. Ended up checking the compression and replacing all the spark plugs, before I said I wanted it. 140-145 psi on all cylinders, low but even. It drove nice, no rust, no visual damage, and so I ended up getting it for 1400 bucks. A decent deal over anything local in the Los Angeles area. Only thing I hated was driving it home like this. It did have a temporary gas and temp gauge. Heating and A/C work very nice.

Got it home and started further inspection. Ripped out all the old POS wiring someone did for a stereo. POS speakers and sub box. My god, who wires things with different size wires, butt spiced together, all in one run? Going from something like 12awg at the battery, to 16awg connected under the bench seat that runs to a sub. Gezz, the 6x9's mounted in the panels were just as bad.

The seats are out of a late model Tahoe. Driver side is electric, but slow. No big deal. Did find out it was mounted with only 2 bolts. The passenger side is manual, mounted with 3 bolts lol. The carpet was decent, looked like it was removed from the same Tahoe, fit ok. All molding and rails were good, headliner too. All windows and locks are electric, they all work ok.

I ended up hating the headliner and sold all the molding for a good price. I didn't like the rear carpet so I ripped it out as well. At the time, I kept the front carpet. After working on it some more and needing to fix the seat mounts, I pulled the front carpet out too.

A little ahead of myself.
Before pulling the carpet or taking anything apart, I checked some other vitals.
I had a trusted transmission shop look over the axles, trans, and transfer case. Replaced a fork, then split and resealed the leaky case on the 208. The trans had a leaky cooler line, the inside look decent enough to hold together for now. Axles are open diffs w/3.73s. Look decent, no replacing at this time.

First of the purchase was realizing not all carbs are "carbs". Some are CCC pieces of joy.

Was driving it one day and it started getting hot. Was closer to Fathers house than my own. Parked it there for a day. Pulled the stat out, added some water, and drove it home.
Ended up replacing some things while I was at it.
Water pump
Larger radiator (stocker had couple pinholes)
new gates belts and hoses
fixed battery cables and battery holder
water neck, gasket, T-stat

Back in business
Took it a little further to Gorman for some climbing tests. Sorry, video is in HD 60fps and the computer can't handle it.

found a fan and on my way out...found some shock towers. Mark8 fan. My friend has one in his OJ Simpson Bronco, seems to work very well, dual speed. The fan's shroud also fits perfectly inside the Blazers stock shroud. I think I'll modify the stock shroud, cutting the unnecessary parts and keeping what is needed for the E-fan.

I joined CK5 cause of it's wealth of info and helpful people. There was so much info I found on suspension setups, long travel shocks, and axles that I thought "even without using the forum again, this info is worth the subscription payment as a thank you." I didn't know the sleepless nights I had coming, so much info and ideas, the damn brain wont turn off lol.

I've collected some parts while driving the truck. What I'm looking to do is a 4" lift, 1" body lift, and 1" 0 rates. I think this will keep the majority of the weight low, but still let me run 35-36" tires w/trimming. The 1" body lift is mainly there to give me room to clock the transfercase. Most of my parts are used or pre-purchased new, trying to save the funds. Got some TC HD4" front springs w/0 rate, rear 56" suburban springs, ORD 4" shackle flip, and some ORD greaseable bolts and front shackles. The front 0 rates will be moved an inch forward.

More parts in the garage than on the truck. I also picked up some D44 flat top knuckles and had the one machined. I learned a little bit about pressing in ball joints, so I bought a harbor freight special ball joint/ u joint press. I'm hoping that was the hard part, but I've read torquing them is the funnest. O, and I'm learning how much it sucks to buy parts and change your mind. Anyone need a new fan clutch or swag bar bushings?
