There are a lot of single-cab, short-bed classic GM trucks out there. Chevrolet and GMC pumped out a lot of them, and their handsome looks and simplicity made them popular with customizers long after they were new. This particular 1966 GMC 1500 pickup has that same configuration, but comes in an unusual color combination that separates it from other C/K builds. You’ll have no problem spotting it at the Barrett-Jackson 2025 Palm Beach Auction, which takes place April 24-26 at the South Florida Fairgrounds.
The story goes that the original buyer worked on the Pontiac production line and had this truck painted the lovely color you see here, which in Pontiac parlance is known as Iris Mist. Although that’s paired with pearl white for the top of the cab, this custom truck is officially known as “The Color Purple.”
A father and his two sons worked together to create this instantly recognizable pickup. They started the frame-off build in July 2022. Over the next two years, the trio overhauled the truck entirely. The frame was stiffened, C-notched, equipped with a driveshaft loop, and refinished. Suspension modifications included the installation of Classic Performance Products sway bars and front spindles, Simple.C10 rear suspension kit, and four-corner Air Lift Performance air suspension system, which drops the truck closer to its massive white 22-inch wheels. The family of builders didn’t touch the original paint, but it did add fresh side trim.
There’s a similar two-tone color scheme inside the single cab, which is furnished with purple and white buddy bucket seats. Modern amenities include a 12.3-inch Holley digital gauge cluster, a RetroSound head unit, and Vintage Air climate control.
No custom build would be complete without engine modifications. Under the hood, this GMC has a 5.3-liter V8, which is enhanced by ported heads, Holley Terminator X fuel injection system, upgraded camshaft, chromoly pushrods, and LSA supercharger. Not only does engine punch harder, but it also breathes better because the exhaust system was equipped with headers and Black Widow mufflers. A built 4L60E four-speed automatic transmission with a 3,000-rpm-stall torque converter sends the engine’s increased output to a 3.73:1 rear end with an Eaton locking differential.
The father and sons who put this truck together completed it in time for Hot Rod Drag Week 2024. In just a few weeks, it’ll be crossing the block at the Barrett-Jackson 2025 Palm Beach Auction,. If you place the winning bid, you can take it home and enjoy it with your family.
