1997 GMC Sierra 1500 LT4 Supercharged Restomod
Collectible Motorcar of Atlanta is proud to offer this stunning 1997 GMC Sierra 1500, an exceptionally clean OBS truck that combines original survivor-quality presentation with modern supercharged performance. Finished in its original Summit White paint and retaining an incredibly well-preserved gray cloth interior, this Sierra has been transformed into a professionally built street truck while maintaining the timeless look that made these GMT400 trucks legendary.
Originally equipped with a 5.7L Vortec V8, this GMC now features a fresh Gen V LT1 6.2L V8 topped with an LT4 supercharger. The engine build was completed with performance and reliability in mind, utilizing ARP rod bolts, King race bearings, upgraded oil pump, BTR 225 camshaft kit, DOD delete, Morel lifters, upgraded trunnions, new timing chain, fresh gaskets, and a Holley oil pan. Feeding the supercharged LT1 is a polished Wegner front serpentine drive system with a 5% overdrive setup that creates an engine bay worthy of any show field.
Backing the LT1 is a modern 8L90E automatic transmission equipped with a Circle D 3,400 RPM converter, Tru-Cool 40K transmission cooler, braided AN plumbing, and an aluminum driveshaft. Power is transferred to a narrowed and rebuilt rear axle featuring Yukon positraction, Moser axles, new bearings, races, and 3.42 gears.
The chassis has been extensively upgraded to handle the truck's performance capabilities while delivering an aggressive stance. Suspension modifications include a Suspension Engineering crossmember, Stone Fab narrowed front control arms, Viking coilovers, splined sway bar, Reklez 10-inch under-bed notch with shock relocation kit, QA1 rear shocks, flip kit, shackles, Reklez 2-inch blocks, and Cal-Trac traction bars.
Stopping power is equally impressive thanks to Little Shop Manufacturing 16-inch four-wheel disc brakes paired with a Wilwood master cylinder and adjustable proportioning valve. The truck sits on staggered polished Intro wheels measuring 22x9 inches in the front and 22x10.5 inches in the rear wrapped in 265/30ZR22 and 295/30ZR22 performance tires.
The exhaust system consists of 1-7/8-inch long-tube headers feeding a fully V-banded 3-inch dual exhaust system equipped with Borla Pro-XS mufflers, creating an aggressive sound without sacrificing drivability.
Inside, the truck remains remarkably original and exceptionally clean while incorporating modern upgrades throughout. Dakota Digital VHX gauges, Dakota Digital fan controller, GSS-3000 gear selector, BIM module, Kenwood touchscreen head unit, custom-painted Metra dash bezel, and a premium audio system featuring Kicker and Infinity speakers, dual Kicker Solo-Baric 10-inch subwoofers, custom-matched enclosure, and dedicated amplifiers provide modern comfort and convenience.
The attention to detail throughout the build is outstanding. The engine bay features Slosh Tubz inner fenders, filler panels, battery box, radiator cover, smoothed and painted firewall and core support, polished reservoirs, polished Wegner accessory drive, All American Billet hood hinges, LG billet accessories, PSI wiring harness, aluminum radiator with electric fans, and stainless hardware throughout.
Additional upgrades include Aeromotive fuel regulation, Walbro 450 fuel pump, braided fuel lines with black AN fittings, Borgeson steering shaft, LED lighting conversion, Dynamat sound deadening throughout the cab, Street Scene sport mirrors, EZ Clip A/C system, ceramic window tint, and numerous custom touches that showcase the quality of the build.
Perhaps most impressive is how well this truck retains its original character. The original paint presents beautifully, the original interior remains exceptionally clean, and the truck comes with its original owner's manuals, window sticker, receipts, and magazine feature documentation.
The air conditioning blows ice cold, the heat works exactly as it should, and the truck starts, drives, and performs as a properly sorted modern restomod should.
This is not a hastily assembled OBS truck. It is a thoughtfully built, professionally executed Sierra that combines original survivor quality with modern LT4 supercharged power, overdrive transmission technology, exceptional road manners, and show-quality presentation.
Whether you're looking for a high-end show truck, a weekend cruiser, or one of the cleanest LT-powered OBS builds on the market, this GMC Sierra delivers on every level.
