Get a Look at Street Trucks Magazine’s Project Rocky 1979 Squarebody

Street Trucks magazine has spent most of 2022 building Project Rocky, a two-wheel drive 1979 Chevy C10 with a four-inch lift and 33 inch Toyo Open Country A/T III tires mounted on 22 x 12 American Force Guardian SS wheels. Naturally, Street Trucks wanted to power the truck with an LS engine, and naturally they found what they wanted at Summit Racing.

The foundation is a Summit Racing™ Chevy LS 5.3L 450HP Long Block Crate Engine machined and assembled by ATK Engines. Based on an iron block with factory internals, it has a Summit Racing Pro LS roller camshaft (222°/232° duration @ .050, .550" lift) that helps push output to 450 horsepower and 420 lbs.-ft. of torque.

Street Trucks outfitted the engine with a Lokar LS Classic Series intake kit and valve covers to give the LS the look of a Gen 1 small block Chevy. The intake is fitted with a 92mm Summit Racing™ Billet Throttle Body and 42 lb.-hr. Holley fuel injectors. Fuel and spark are controlled with a Holley Terminator X MAX engine management system.

The 5.3L is connected to a TCI 4X StreetFighter 4L60E transmission that comes in a kit with a Breakaway torque converter, a transmission cooler, filler tube and dipstick, and three gallons of Max Shift transmission fluid.
