Restored, Vortec-Swapped 1968 Chevy C20 Longhorn Is Up For Auction

This 1968 Chevrolet C20 Longhorn pickup truck is currently available for sale via an online auction on bringatrailer.com. This particular C20 Longhorn caught our eye for how great of a shape it’s, undoubtedly thanks to a refurbishment performed in 2010. It now features Anniversary Gold paintwork with a gray cloth interior.

A more major change has been the fitment of a Vortec 5300 V8 from GM’s LS family of engines. This motor is said to have come from a 2003 GMC Sierra and is therefore likely an LM7 rated at 285 horsepower and 325 pound-feet of torque. It has been fitted with a K&N cone-filter air intake.

Power is taken to all four wheels through a three-speed TH350 (Turbo-Hydramatic) automatic transmission, a two-speed transfer case and ten-bolt front and 12-bolt rear axles.

The mileage is unknown, but the odometer reads 1,500 miles, which is believed to be how far the truck has traveled since its refurbishment.

Modern updates to this Chevy C20 Longhorn include a JVC CD player and speakers, later-model seats, power locks, power steering, front disk brakes and a Vintage Air climate control system. The underside of the cab has been covered with undercoating material.

The selling dealer, Cotton Warehouse Classic Cars of Batesville, Mississippi, acquired the truck in March 2019, and states that the steering column was rebuilt in preparation for this sale.

1968 was the second year of the second-generation Chevrolet C/K truck, and the first of the Longhorn variant. The Longhorn frame was six inches longer than that of the regular C/K, extending the wheelbase to 133 inches and the bed length to eight and a half feet. This iteration of the C/K was replaced by the third-generation version for the 1973 model year. The current equivalents of the truck are the 2021 Chevy Silverado and the 2021 GMC Sierra in Regular Cab guise.

The auction will end on the evening of January 4th and the bid, as of this writing, is $12,500.

  1. Looks great , but I would never be interested in anything cobbled together from different year trucks and parts if it isn’t close to original they can keep it

    1. Well then you won’t mind me cutting in line in front of you! 😁

  2. Looks like a C10 to me. 6 bolt wheels and maybe someone can’t read, but the emblem looks to indicate C10.

  3. Many years ago I had a ’72 Longhorn. It was a C20. I don’t think the longhorn was made in a C10 because they were made to carry a 12′ slide in camper that was 8 1/2′ in bed 3 1/2′ overhang. That size camper is way too heavy for a 1/2 ton. The one in this article has 1/2 ton axles, and doesn’t have the seam 6″ back on the bed where the extra length is added. Mine had a wooden floor because they didn’t make a steel floor that length.

    2. I agree with Marc, my 68 longhorn had 8 lug wheels and had a seam 6 inches back from the front of the to make the extra bed length. Also only came 20 series, 3/4ton.

      1. The longhorn edition was only made in 3/4 ton class so the truck in this article is a fake from the start

      2. My father got one new in longhorn it had six cyl four SPD and it was real hard to buy a camper it at the time

  4. Wouldn’t this be a K series, and not a C, as it is 4WD, or didn’t they use that designation on this era of truck?

  5. You guys kill me. Setting there bone picking is
    Truck apart. I think it’s a great looking build. Maybe the editor miss spoke. Are just maybe the builder used what he had at his desposil. Either way I Love it. The builder was obviously thinking out side the box. I would love to beat the snot out of this truck in the woods of Florida. Then three hours on the interstate.
    I bet it would be a perfect day.
    You guys should get together buy a truck an see what you come up with. It’s not all about the build. It some of the fact that it’s not crushed in to a soup can. One more survivor.
    I’m building a 61 Apache step side. On a 75 k5 on 40″ tires. I started with a number matching truck. 265 v8, three on the tree. All of the sheat metal work was done. And thousands of dollars of new factory parts. It will be a great build. Not worth what it could be with little effort. But what I want. 700 hp 454.
    Enjoy life, it’s short. And yes one more survivor.

  6. Say what you will but it’s just a plain jane resto mod truck cobbled up interbred with other year components, sure it looks nice would I want it ? probably not its fun to look at but its a white elephant in my eyes

  7. Trust folks to rip up any post line they wish to troll. I agree that the initial description of this specific vehicle is in error. This looks to be a k-10 longbed truck that has been modded. With that in mind it is entirely possible that the initial description was received from the auction post which seems fabricated to increase the value of the truck.
    Don’t kill the messenger.

    As for those believing the truck is not worth the 12k that was the ‘latest bid’ y’all have much better supply lines than I do.
    I am currently restoring a 74 el camino classic 400 and finding parts that are of original production is harder than pulling snake molars. As an example.. The top trim piece on the tailgate is $800. Minimum. If you can find one. The restos are not cheap.
    To flame others one should have one to compare.
    If not? Meh. You’re nothing but a troll
