Topless: 1972 Chevrolet K5 Blazer CST

This 1972 Chevrolet K5 blazer is located in Marietta, New York. The truck is for sale here on eBay with four days remaining in the auction. Currently, there are 18 bids but the reserve has not been met. The current high bid is $23,300. The seller states that this is a solid strong and easy driving truck. The eBay ad has several good pictures of the truck with two different tops – fabric and hard top. Pictures of the undercarriage indicate that the truck is solid and rust free.

The truck is equipped with a rebuilt Chevrolet 350 cubic inch V8 engine which has been modified with a mild performance camshaft, Holley carburetor, MSD ignition and headers. The K5 Blazer was originally purchased in the state of Colorado. The gearbox for the steering was recently replaced and the 5.7 liter V8 engine is backed by a rebuilt manual transmission with a low first gear for towing. Aftermarket valve covers have also added.

The interior looks sharp and an aftermarket radio is mounted under the dash. A tachometer is mounted on the steering column and almost looks like a factory gauge. The odometer reads 42,330 miles but the seller states that he actual miles are unknown. The seller states truck was born as a CST which stands for “Custom Sport Truck.” The air conditioning compressor was removed and the automatic transmission was replaced with the manual shifting transmission. The black soft top looks relatively new and the truck comes with a hardtop that has a crack in it and will need repair. The driver has had this truck for roughly 20 years period.

Four wheel drive Chevrolet Blazers are popular and many enthusiasts love the front egg crate grill on the 1972 model. This K5 Blazer is equipped with the factory Chevrolet rally wheels and oversized aftermarket tires. The seller states that the truck runs great. It looks great with the top down.

    Bought a solid white with black hard top new in ’72 with the 4 speed trans and 4 wheel drive. 350 with a 4 barrel and a great overall truck to do most anything with. In our case we towed race cars and occasional camping with it. Only problem we had was internal rust from the factory that required taking everything off the frame eight months later but the cowl/cab portion to paint and rustproof everything. Great rig. Got 11 mpg regardless what we did with it so added a second fuel tank. Glad to see one still in one piece. Best looking of the many similar models out there at the time.

    We started seeing these in ‘69 and they really took off with the ‘71-‘72 models being the most popular. It wasn’t long before the Blazer/Jimmy replaced the family car. The vast majority of the ones out west were powered by 350 engines which were NOT all that economical. But a little fine-tuning usually smartened them right up. Smog regulations were already in effect, mostly in the form of lean mixtures and retarded advance curves. Up a couple of sizes in jets and dial in the advance so that it actually ADVANCED under 3000 rpm and it was amazing how much better they ran.

    Now for this truck. There’s a lot of modifications you can do to these with a visit to the local salvage yard, something which I suspect has already been done. That soft top would last about three minutes on a windy day in the Chinook Belt so it would be best to fold it up and put it away. Fix the hard top and use it. Good truck overall but get used to the wind whistles…
