A 1970 Chevrolet Chevelle with black paint, perfect stance, and a supercharged LSX under the hood is usually the kind of build you expect to see parked under lights at a major indoor show. This one is different because its owner actually drives it.
Built by Junior and the team at Backyard Specialties, the Chevelle recently appeared on Autotopia LA, where it proved to be far more than a pretty pro-touring display car. It is brutally powerful, beautifully detailed, and surprisingly livable on the road.
The car started as what looked like a decent project, but that changed once the work began. According to Junior, almost everything ended up being replaced because repairing the original panels would have cost more than using quality reproduction parts.
The result is a serious street machine with roughly 750 horsepower at the rear wheels. Factoring in drivetrain loss, that puts the supercharged Chevelle somewhere close to 900 horsepower at the crank.
Supercharged LSX Power
Under the hood sits a GM Performance LSX 376 crate engine. The low-compression small-block was chosen specifically because the owner wanted boost, big power, and a proper supercharger whine.
After speaking with Tom Nelson, the team selected a Kong Performance supercharger setup. The combination delivered more than expected, producing about 750 horsepower to the rear wheels on the dyno.
That power runs through an upgraded T56 six-speed manual transmission from American Powertrain. Out back, the car uses a Ford 9-inch rear end with gearing chosen to give the Chevelle serious low- and mid-range punch.
The throttle was initially so aggressive that the team later softened the pedal response. That made the car easier to drive regularly without constantly feeling like it wanted to explode forward.
A Chassis Built To Handle It
Backyard Specialties did not leave the Chevelle riding on its original frame. Once the owner explained how hard he planned to drive it, the team installed a Speedtech Performance Extreme chassis.
The setup includes modern suspension geometry and a torque-arm rear suspension. Wilwood brakes provide stopping power, and the car uses a manual brake setup that Autotopia LA’s Shawn Davis praised for its pedal feel.
The Chevelle rides on Compression wheels measuring 20×10 inches up front and 20×12.5 inches in the rear. To fit the massive 345-section rear tires, the team mini-tubbed the car and modified the rear structure for extra clearance.
That tire and chassis combination gives the car real composure. Even during hard acceleration and burnouts, the Chevelle stays planted instead of feeling sketchy or unpredictable.
Subtle Bodywork Makes A Big Difference
The exterior looks clean at first glance, but there are plenty of careful custom touches. The bumpers were tucked tighter to the body, and the rear bumper was reworked into a cleaner one-piece design.
The car also wears Ringbrothers mirrors and hood hinges, along with an Ironworks front spoiler. That spoiler helps visually lower the nose without ruining ground clearance.
There are no excessive badges or overdone graphics. The black paint, aggressive stance, wide wheels, and visible brakes do most of the talking.
A Clean Interior With Clever Details
The interior follows the same philosophy as the rest of the build. It is modernized, but it still feels like a Chevelle rather than a completely new car wearing old sheetmetal.
California Upholstery handled the cabin, using a clean mix of leather, custom door panels, and a full center console. The seats are modified Hyundai Veloster units, reshaped and trimmed to sit low enough that they do not dominate the classic greenhouse.
The car also features Dakota Digital gauges, Vintage Air, Bluetooth audio, and front and rear cameras displayed through the rearview mirror. It is a smart setup because it adds modern usability without cluttering the dashboard with a huge screen.
Built To Be Enjoyed
The best part of this Chevelle is that it is not treated like a fragile trophy. The owner drives it regularly around Southern California, which explains why the build was tuned for comfort, control, and reliability rather than just maximum shock value.
Autotopia LA host Shawn repeatedly praised how natural the car felt from behind the wheel. The driving position, shifter placement, brake feel, suspension tuning, and exhaust note all worked together instead of fighting the driver.
That balance is what makes the build special. Plenty of classic muscle cars can make huge power, but far fewer can do it while still feeling refined enough for a long cruise.
Backyard Specialties built a Chevelle that looks stunning, sounds angry, and has enough supercharged power to scare almost anything on the road. Better still, it gets used exactly the way a car like this should.
