Bring A Trailer has always been an incredible place to ogle over the cars and trucks we dream about. The auction site has seen some seriously cool metal come across the block during the ongoing coronavirus pandemic, including this perfectly-vintage 430 horsepower LS3-swapped 1972 GMC K10 Sierra Grande.
According to the auction listing, this 1972 GMC K10 was sold new in Arizona where it lived before being purchased by the seller in 2018. In the time since, the truck has undergone a total restoration, the crown jewel of which is a Chevrolet Performance LS3 crate motor. The modern engine was installed with a Dirty Dingo Motorsports swap kit, and is fitted with a A BeCool aluminum radiator, a cold air intake and other performance modifications. Power is sent to the 4×4 transfer case via a 4L65E four-speed automatic transmission.
After the truck was resprayed in its factory yellow and white two-tone color, the entire undercarriage was powder coated for future rust prevention. A 4″ Rough Country suspension lift was also installed, making room for a set of 33-inch BFGoodrich All-Terrain T/A tires mounted on 15-inch OEM Rally wheels. All of the exterior trim has also been replaced, and the bed of this “wide side” GMC K-1500 has also been refurbished. Inside the all-new houndstooth interior, you can find modern amenities like a set of Dakota Digital gauges, a Vintage Air HVAC system and even a Bluetooth-ready stereo.
This LS3-swapped 1972 GMC K10 Sierra Grande was bid up to a price of $78,200, however that was not quite enough to meet the sellers reserve. The seller mentioned in the comment section of the auction that the truck was built to be sold, and that they have sunk over $100,000 in hard costs into the truck. If you are interested in purchasing this truck, it was built by Woodys, Wagens & Classic Cruisers, LLC. We’re sure they could be convinced to part with it for the right price.
