Spending heavily on a modified car rarely guarantees getting that money back, and this 2022 Chevrolet Camaro ZL1 1LE is a particularly brutal example. Its seller poured tens of thousands of dollars into turning an already serious factory muscle car into something built to handle four-digit horsepower.
The finished Camaro combines a purpose-built 390-cubic-inch V8, a large Magnuson supercharger, upgraded fueling, a strengthened six-speed manual transmission, and enough supporting hardware to make its original specification seem almost restrained. According to the seller, the combination was built with as much as 1,500 horsepower in mind.
The Bring a Trailer listing says the seller acquired the Camaro in 2023 and subsequently spent more than $68,000 on modifications. The auction ended on August 31, 2026, with the car selling for $76,500, meaning the modification bill alone came within $8,500 of the entire sale price.
That figure does not include whatever the seller originally paid to buy the ZL1 1LE in the first place. While the exact total investment is not disclosed, it is safe to say the build represented a substantial financial loss by the time the hammer fell.
The Factory LT4 Is Long Gone
The centerpiece of the build is a 390-cubic-inch V8 assembled by Late Model Engines and installed in 2024 by Complete Street Performance. Internally, it uses forged pistons, connecting rods, and crankshaft components, along with a custom camshaft, upgraded valvetrain parts, ported cylinder heads, and extensive supporting hardware.
Sitting on top is a Kong-ported Magnuson 2650 supercharger fed through a large Nick Williams throttle body and Roto-Fab intake. The car also uses a Forced Inductions Interchiller, triple fuel pumps, and supplemental port injection to support the significantly increased airflow and fuel demands.
The seller claimed the setup could support around 1,500 horsepower, although Bring a Trailer does not list a dyno sheet confirming that output, making the figure a claimed capability rather than a verified measured result.
The Six-Speed Was Upgraded Too
Sending that kind of power through a factory transmission would be asking for trouble, so the Camaro’s six-speed manual was rebuilt with stronger components. The transmission features a forged main shaft, upgraded bearings, bronze fork pads, and a revised sixth gear.
A Monster LT1-S triple-disc clutch was added to help cope with the increased torque. Long-tube headers and high-flow catalysts complete the major drivetrain changes, giving the car a much more serious mechanical package than a stock ZL1.
It Still Has The ZL1 1LE Hardware
Underneath all the engine work remains the factory ZL1 1LE foundation. That includes Multimatic DSSV dampers, an electronic limited-slip differential, Brembo brakes, a three-way adjustable rear stabilizer bar, and 19-inch wheels.
The car has 15,000 miles on the chassis, with approximately 14,000 of those accumulated by the seller. Its Carfax report is free of accident or damage entries, while the Shadow Gray Metallic exterior and Jet Black leather and suede interior retain the familiar factory appearance.
$68,000 In Mods, $76,500 Sale Price
The final $76,500 result looks attractive from the buyer’s perspective once the build sheet is taken into account. Someone effectively bought an entire ZL1 1LE along with over $68,000 worth of documented modification work for only slightly more than the cost of those upgrades alone.
The seller’s side of the equation is far harder to celebrate. Without even knowing the Camaro’s original purchase price, the numbers already show just how little of that modification spending came back at resale.
It is an expensive reminder that building the car you want can cost a fortune, while finding the next person willing to pay for that vision is another matter entirely.
