The standard 1991 GMC Sierra provides respectable performance that satisfies most owners. However, some crave more under their right foot, and this truck delivers for potential buyers who feel that way. Its original V8 has made way for a potent LS featuring a range of updates to maximize its performance. The spotless exterior and interior are the final pieces of the puzzle, with this Sierra guaranteed to turn heads and command attention. The current owner is ready to move on to other projects, so he has listed this beauty exclusively with us at Barn Finds Auctions.
This Sierra makes a positive first impression, from its sparkling Bright Blue paint to the stunning 20″ Venti wheels. The current owner located the truck sitting under a carport, and with one side exposed to UV rays, the original paint had become faded. Therefore, he treated it to a repaint in the original shade, applying the finish to steel that is as straight as an arrow. Rust is not an issue with this dry-climate classic, with the underside shots confirming it is as solid as the day it left the factory. The decision to Rhino-line the bed means it will withstand punishment if the winning bidder makes full use of its load-carrying capabilities. The bright trim provides a striking contrast to the relatively dark paint shade, with the wheel arch moldings particularly noteworthy for adding a classy edge to the appearance. The tinted glass is spotless, representing the perfect finishing touch on a Sierra that has no cosmetic or structural needs.
Lifting the hood reveals where much of the $35,000 the owner invested into this project went. The VIN decodes to confirm that the first owner ordered it with the 350 TBI V8 that produced 190hp and 300 ft/lbs of torque. Almost every owner wants a bit more power under their right foot, but this Sierra now generates a lot more. Forget 190hp, because this 5.3-liter LS beast delivers over 400hp. It sends those ponies to the road via a four-speed 4L60-E automatic transmission. This may now be a genuine muscle truck, but the presence of power assistance for the steering and brakes means the driver doesn’t need muscles to maneuver this beauty. The LS produces most of its power courtesy of improved breathing. The FiTech fuel injection system feeds air and fuel into the engine, while ceramic-coated long-tube headers and Magnaflow mufflers dispose of the spent gases. The owner didn’t leave any stones unturned during this build, replacing a long list of parts that included the power steering pump, water pump, starter, oil pan, and miscellaneous small items. He rounded out the engine bay package with a Dirty Dingo Billet Pulley system that adds to the already spotless presentation. It is worth noting that while the odometer reading of 124,000 miles is well below average, only 1,000 of those have rolled under this truck’s tires since the mechanical refurbishment ended. Potential buyers can consider this a turnkey proposition that will comfortably show a standard Sierra a clean set of heels.
This Sierra’s interior is quite subtle and restrained, providing few clues as to how potent this package is. Its presentation is as clean and tidy as you would hope to find in any driver-grade classic. The Blue cloth and vinyl trim is free from wear and physical damage, with the same true of the carpet and dash. The owner splashed the cash on a new headliner and dash cover, treating the air conditioning to a new compressor during the build. Other creature comforts include power windows, power locks, a tilt wheel, and the factory AM/FM radio/cassette player.
Daily driver? Weekend cruiser? Eye-catching shop truck? Those are a few of the possibilities provided by this 1991 GMC Sierra. It will provide the new owner with an effortless driving experience, while the inherent economy provided by electronic fuel injection could make it a viable daily driver. However, many people would look at slipping behind the wheel on the weekend as the perfect way to escape from the humdrum 9-to-5 existence they experience from Monday to Friday. That sounds mighty tempting, and there could be no better reason to submit a bid and make the vision a reality.

Comments
Early 90s GM pickups are really nice looking, and this one not only shreds the quarter mile but also its back tires! I do wish they would have sprung for an updated speedometer without the 80 mph limit, because when you’re going 120 you won’t know it!
No Tach either, I had an 89′ C1500 Scottsdale (Vinyl bucket seats, rubber floor, console) with 350 and 5 Speed, hose clamped a Sun Tach on the Column, loved that Truck, finally sold it in 2000 when I got stationed in DC and it wouldn’t fit in the parking garage
In the mid nineties I worked at a service center that sold any and all car gauges. I’d have had a ball with this truck.
Lose the ox cart wheels.
But they’re shiny! Loose ’em, I agree. Something more subtle would make this a great sleeper. I’m thinking this little truck is strictly a straight line proposition.
Whelp, here it is. LS swap already done. No, as poor as those wheels look you’re going to want that rubber every time you start, steer and stop. The low speed speedometer comes back around again so if you’re ok with math you’ll know how fast you’re going. Power steering and brakes became standard in 1988.
A beauty, but my 20m12 with ONLY a 4.8 280 hp is just as lovely and wit 20 inch Cragar’s and new tires. When I buy the 58 Caballero I;ll have my 2 dr short bed on the market for about $20 K, Black and beautiful
How much are you kinda looking for? Would be nice to know a reserve I reckon.. don’t wanna bid and end up not getting it even when the highest bidder.
