This 1963 Pontiac Tempest is an extraordinary one-off custom build created with virtually no compromises. Finished in a striking metallic brown over a completely bespoke tan leather interior, virtually every aspect of the car has been reengineered, fabricated, or refinished. From its radically modified body and show-finished chassis to its dyno-proven Butler Pontiac powerplant, this is far beyond a conventional restomod. The sheer scope of the fabrication, components, engineering, and finish work represents a substantial six-figure build, with extensive receipts, dyno sheets, engine specifications, and supporting documentation included with the car.

At the heart of the Tempest is a Butler-built 459ci Pontiac V8 producing a dyno-proven 795 horsepower. The engine is topped by an imposing polished supercharger and dual C&S 850 carburetors, with the induction system extending prominently through the custom-fabricated hood. An Aeroquip-equipped fuel system supports the combination, while a custom Be Cool modular cooling system incorporates a separate transmission cooler and dedicated fan. The engine compartment itself is finished to show-car standards with extensive polished and chromed components, braided lines, fabricated panels, and meticulous detailing throughout.

Power is sent through a Rosler-built Turbo 400 automatic transmission equipped with a Coan torque converter and back to a Moser Ford 9-inch rear end. The chassis received equally extensive attention, featuring a four-link rear suspension, coilovers, power rack-and-pinion steering, and Wilwood four-wheel disc brakes. Much of the chassis, suspension, and driveline has been chromed, polished, or finished to complement the exterior, creating an undercarriage designed to be every bit as impressive as the top side of the car. Despite its extreme appearance and nearly 800 horsepower, this Tempest was built as a street-driven car and has never been professionally raced.

The body has been extensively modified while retaining the unmistakable profile of the 1963 Tempest. The wheelbase was altered approximately three inches forward, helping create its dramatic Pro Street proportions. The drip rails were shaved and smoothed, exterior moldings were removed, and the fuel filler was frenched into the quarter panel. Custom inner fenders were fabricated, the front fenders received enhanced louvers, and the hood was specifically formed around the massive blower assembly. Flush-mounted, radiused Lexan front and rear windows with a coated finish further contribute to the car's competition-inspired appearance, while the stock side glass remains in place with tint.

At the rear, extensive hand fabrication includes a custom fuel tank, rear valance, and prominent fabricated rear spoiler with support rods. A customized rear panel and taillight treatment further distinguish the car from a stock Tempest, while side-exit exhaust outlets just ahead of the rear wheels add another aggressive detail. Weld Racing wheels complete the Pro Street stance, with massive 33x20x15 Mickey Thompson Sportsman S/R rear tires tucked beneath the quarters and 26x6 fronts providing the classic narrow-front, wide-rear profile.

The interior is every bit as elaborate as the exterior. Custom bucket seats are finished in tan leather with contrasting brown patterned inserts, a theme carried throughout the full-length center console, door panels, and additional interior surfaces. A completely custom dashboard houses a full complement of AutoMeter instrumentation, with additional gauges incorporated into the lower dash. A custom steering wheel, performance floor shifter, race belts, and color-coordinated integrated roll cage reinforce the car's performance character while maintaining the high level of finish found throughout the build.

Street usability was clearly an important part of the project. The Tempest features working Vintage Air heat and air conditioning, power windows, electrically operated doors with custom manual-style handles, and a seven-speaker AM/FM/CD sound system. The custom treatment extends overhead with a fully finished headliner and integrated overhead console. Even the trunk received the same attention to detail, incorporating finished panels, matching upholstery, color-coordinated chassis structure, a fabricated aluminum fuel tank, and relocated electrical components.

This is the type of build where the details become more impressive the closer you look. The extensive hand-fabricated bodywork, completely bespoke interior, chromed chassis, purpose-built suspension, show-quality engine compartment, and dyno-proven 795-horsepower Butler Pontiac drivetrain represent an enormous investment in both time and craftsmanship. The accompanying build receipts and documentation further illustrate the extraordinary scope of the project.

For the collector looking for something that simply cannot be duplicated by finding another example, this 1963 Pontiac Tempest offers exactly that. It is a fully documented, one-off Pro Street custom combining exceptional craftsmanship and show-car presentation with serious Pontiac performance and genuine street capability. Build receipts, dyno sheets, engine specifications, and accompanying documentation are included with the purchase.

Price does not include applicable tax, title, license, processing, and/or $240 documentation fees.
