Roy,
You need to give a bit more info... what shape is the interior in? what color is it? how many miles? any specific upgrades already done?

What year?

[dboat]

Is it missing the hood or is is just removed for now?

Looks clean to me and this may be a really good deal depending on the year, trim level(appears to be a Silverado), axles/gear ratios, transmission, suspension, mileage, upgrades, and truck's location history, rust can be an issue on K5s.
Need details.

Anyone that buys this, the best thing to do is to put an 87-up transmission in it (junkyard) and a large fluid cooler. GM beefed up the internals on the 87 model to prevent failures.

My buddy had an 85 model K5 that blew multiple transmissions, he gave up and put a turbo 400 in it. My 87 model with the 700R4 OD transmission had 145K or so on it when I sold it and was still going strong. I had 33" oversized tires, a massive audio system and about 100HP over stock. I blew out 3 factory 10 bolt rear ends, then upgraded to a 12 bolt (blew that too) and then finally upgraded to a Ford 9", but the tranny held! I drove mine hard, took it off road a lot and did a lot of city driving, so I was about as hard on it as anyone could be.

Common problems with this model: There is a bushing in the transfer case that will chatter a bit when coasting if it gets too worn, it's a cheap part but you have to remove the t-case to change it. Stock rear doesn't like on pavement burnouts, especially if posi, and especially with big tires and HP mods. The stock motor will run basically forever unless you do something stupid!:d

Other than that, these trucks are very capable off roaders and super reliable as a DD. Stock, they get about the same mileage as our trucks. The engine bay is huge so it's easy to work on and parts are super cheap as they are compatible with so many cross-models. AC will work better if you insulate the rear topper (glue on sheets, then put a headliner on it to look perty).

If you want a fun toy or a good work truck, this would be a great deal for you!

Just my opinion, your results may vary:beer:

In 1973, GM's line of full-size trucks was redesigned and updated. Although rear-wheel drive (http://en.wikipedia.org/wiki/Rear-wheel_drive) Blazers were manufactured until 1982, the majority sold were four-wheel drive (http://en.wikipedia.org/wiki/Four-wheel_drive).
Until 1975, the K5 had a removable convertible top. In 1976, a half-cab design was introduced used until 1991.[1] (http://en.wikipedia.org/wiki/Chevrolet_K5_Blazer#cite_note-specs-76-0)[2] (http://en.wikipedia.org/wiki/Chevrolet_K5_Blazer#cite_note-76p4-1)
Although the GMT400 platform (http://en.wikipedia.org/wiki/GM_GMT_platform#GMT_400) was introduced in the spring of 1987 as a 1988 model, the K5 Blazer, Suburban, and crew-cab trucks retained the earlier platform until 1991. In 1989, the front grille was changed to resemble the squared-off ones used on the GMT400 series of pickups.
The K5 Blazer is very popular in the off-roading (http://en.wikipedia.org/wiki/Off-road) scene. It is a strong truck with the 350 V8 (which was the optional power plant), the gear driven NP-205 and 10- and 12-bolt axles (http://en.wikipedia.org/wiki/Axle). It is very easy to upgrade this engine, because there are many companies with performance parts available. Later models produced after 1980 used the chain-driven NP208 transfer case, and the NP241 after 1988.
Since 1981 (in the wake of the 1973 Arab Oil Embargo (http://en.wikipedia.org/wiki/1973_oil_crisis) and the 1979 energy crisis (http://en.wikipedia.org/wiki/1979_energy_crisis)), Chevrolet and GMC used the smaller displacement 305s with a 9.2:1 compression ratio. These engines produced nearly as much torque as the 350, giving a similar driving feel. However, these power plants were underpowered and susceptible to detonation (http://en.wikipedia.org/wiki/Detonation) (engine knocking (http://en.wikipedia.org/wiki/Engine_knocking)), especially with the electronic spark control module. To achieve the 9.2:1 compression ratio, the cylinder head chambers were smaller, measuring 54 cc instead of 60 cc. Despite a camshaft swap, some Blazer owners swapped out the 305s in favor of 350s, since the smaller displacement power plant was used in all Chevrolet/GMC pickups and passenger cars. 1982 saw the Detroit Diesel 6.2 introduced.

After 1987, when throttle-body injection (http://en.wikipedia.org/wiki/Fuel_injection#Throttle_body_injection) was introduced in the truck engines, the 350 was made the standard power plant.

I can vouch for the knocking and lack of power from the 305's. I had an '85 GMC Sierra with the 305 and that thing always knocked. :icon_cry:
