Steve Locklin's 1970 C10 (outfitted with a 1967 nose) is one of the nation's best-known trucks and features the 525-horsepower mill under the hood. The engine is based on the original 6.2L LS3* but makes those 525 horses and 486 lb.-ft. of torque thanks to an aggressive ASA hydraulic roller camshaft.
The cam features .525-inch lift on both sides, as well as 226 degrees duration on the intake side and 236 degrees on the exhaust side. In addition, the cam has a tight 110-degree lobe separation angle. The result for the engine is exceptional throttle response and outstanding breathability at high rpm. In addition, the team at Chevrolet Performance has complemented the ASA camshaft with higher-rate valve springs for enhanced durability.
But not only does this valvetrain setup provide enhanced power, it also creates a musical exhaust note.
"The 525 has that lope to it and it just sounds awesome," Locklin said during this summer's Goodguys Summit Racing Nationals presented by PPG in Columbus, Ohio.
Today, we've made an image of Locklin's LS376/525 from the show into a Wallpaper Wednesday download. His is topped with a Camaro engine cover to give the truck just one more unique touch.
