Gateway Classic Cars of Dallas is excited to offer This 2003 Chevrolet Corvette Z06, a purpose-built American performance icon that has been extensively upgraded into a true street and strip monster. Finished in a sleek Silver exterior over a Black leather interior, this Z06 combines the raw, lightweight nature of the C5 platform with a meticulously built and boosted drivetrain.
Under the hood lies a professionally rebuilt LS6 V8, completed at approximately 27,000 miles and upgraded with forged pistons (.05 over) and forged rods for strength under boost. The cylinder heads have been checked and refreshed, now paired with upgraded roller rockers and LS7 lifters for improved valvetrain reliability at high RPM.
Feeding this built engine is an ECS (East Coast Supercharging) Novi 1500 centrifugal supercharger system, originally installed by Corvette World of Houston. Supporting the boost are 60 lb injectors and a BTR Stage 3 blower camshaft, along with upgraded pushrods and valve springs with titanium retainers. Tuned on 93 octane at approximately 10 psi by Futral Motorsports in Louisiana, this setup is estimated to produce in the neighborhood of 700 horsepower-delivering explosive acceleration and relentless top-end pull.
Power is sent through a 6-speed manual transmission equipped with a Tick Performance LS7 clutch and flywheel kit, paired with a remote bleeder for easier maintenance. Shifting is enhanced with an MGW short-throw shifter topped with a C6-style knob, providing precise and confident gear engagement.
The exhaust system has been fully upgraded with Hooker long tube headers and a catless full exhaust, giving this Z06 an aggressive tone to match its performance. With approximately 34,000 miles on the chassis, this Corvette represents a well-sorted, low-mile, high-horsepower build.
Inside, the cockpit remains clean and driver-focused, featuring supportive black leather sport seats, a straightforward gauge layout, and the unmistakable feel of a purpose-built performance car. Everything about this Z06 emphasizes driving engagement, from the mechanical feel of the drivetrain to the responsiveness of the chassis.
Whether you're looking for a high-horsepower street car, a roll-racing weapon, or a standout addition to your collection, this ProCharged and built Z06 offers supercar-level performance with proven upgrades and serious attention to detail.
