Car builder Chuck Mallett of Mallett Cars has been known to lend his expertise to a variety of late-model GM performance vehicles. Having established himself years ago as a Camaro and Corvette tuner, and later the exclusive outlet to LS-swapped Pontiac Solstice and Saturn Sky, Chuck has been relatively keeping himself quiet lately. Of course that was until we saw him at the 2014 SEMA Show, where he had a brand new crew cab Silverado sitting inside the Kooks Headers & Exhaust booth.
Packing a Whipple Superchargers-blown 414-cubic inch stroked LT1 powerplant with a forged Callies crank, Manley rods, DI pistons, CNC-ported cylinder heads, a COMP camshaft, a 9.66:1 compression ratio with a complete Kooks engine-to-tailpipe exhaust system, the truck is producing an astonishing 747 rwhp from under the hood. This was accomplished using 15-lbs. of boost and an 8-rib belt being pushed absolutely to its limit. Backing the stroked LT1 is a RevTech 3200-stall converter and a 6L80E transmission.
The Silverado’s mechanical changes are only a fraction of the attributes that consist of the Mallett-tuned Silverado. As Chuck says in the video, the theme of the truck was borrowed from the 1972-era Silverado and Cheyenne C10s of yesteryear – from the two-tone paint, throwback badges and trim, painted steelies and dog dish hubcaps, to the interior trim where brushed steel and houndstooth upholstery recall the Chevrolet vehicles of the time.
Since SEMA however, the truck is being shipped back to Las Vegas, Nevada to find refuge in its new owner’s garage. It’s also been dialed back a bit for the sake of reliability, longevity and to comply with the West Coast 91-octane pump gas. We’re sure the truck’s owner will get a truckload of smiles from this boosted behemoth. We certainly would!
