The 1964 Buick Riviera Custom stands as a testament to the Bill Mitchell era of design, successfully blending sharp, formal lines with a menacing street presence. This specific example has undergone a comprehensive body-off restoration, resulting in a high-caliber build that prioritizes both aesthetic brilliance and mechanical modernization. Finished in House of Kolor Ruby Red Pearl, the vehicle maintains its legendary X-frame architecture while incorporating contemporary performance hardware. Crossing the block at Houston 2026 on Friday, April 10th, this Riviera represents a masterclass in elevating a classic luxury cruiser into a modern pro-touring masterpiece.
Ruby Red Pearl Lustre and Adjustable Air Ride Stance
The visual character of this Riviera is defined by its shimmering Ruby Red Pearl paintwork, which highlights the crisp fender peaks and hidden headlamp aesthetic of the second-year production model. Its aggressive, ground-hugging profile is achieved through a VIAIR front and rear air ride system, allowing the driver to adjust the ride height for both show-floor impact and highway cruising. The truck-mounted air setup is neatly integrated, while the car sits purposefully on 20-inch Billet Specialties wheels with classic spinners. Staggered tires measuring 245/40R20 in the front and 275/35R20 in the rear provide a modern footprint that complements the sharpened silhouette.
Custom Diamond-Stitched Leather and Modern Climate Control
Inside the cabin, the environment is a sophisticated Black sanctuary that maintains the original factory bucket seat layout with a central console and shifter. The interior has been completely refreshed with new seat foam and custom diamond-stitched upholstery that adds a layer of contemporary luxury to the mid-century design. For year-round drivability, the car features air conditioning equipped with a Sanden S6 compressor and an R134A conversion. Convenience is further enhanced by an automatic trunk release hidden in the glovebox and power steering for effortless maneuverability. This cockpit successfully merges the tactile feel of a vintage personal luxury car with the refined comfort of a modern build.
Nailhead V8 Grit and TH400 Automatic Reliability
The mechanical heart of this build is the legendary 425 CI Nailhead V-8 engine, featuring a 4-barrel Carter carburetor and a GM distributor for consistent ignition. This engine provides the massive low-end torque that the Riviera is famous for, exhaling through a dual exhaust system equipped with Flowmaster mufflers for a visceral, deep-toned soundtrack. Power is managed by a TH400 automatic transmission and sent to a Buick 10-bolt rear end with a 3.07:1 gear ratio, offering a perfect balance for highway cruising. While specific horsepower and torque ratings are not provided in the source text, the nailhead architecture remains a favorite for its distinct power delivery and historical significance.
