1981 Cadillac Series 75/Fleetwood for sale
Engine and Performance
Power comes from a supercharged 454ci gasoline V8 fitted with a BDS 671 supercharger and dual-quad Edelbrock carburetors. A three-speed GM TH400 automatic sends power through a narrowed Ford 9-inch rear axle. Together, these components give the Cadillac a character far removed from a conventional luxury sedan. The combination places large-displacement power, supercharger hardware, and custom drivetrain engineering at the center of the build.
Engineering and Specifications
Staggered 15-inch alloy wheels carry 225/75 Michelin Radial XH tires in front and 33×21.5-inch Mickey Thompson Sportsman treaded drag tires at the rear. The rear body has been tubbed to clear the wide tires, while the narrowed axle is located by a four-link suspension. The resulting hardware gives the car its unmistakable pro-street stance and accommodates the exceptionally wide rear tire package.
Design and Heritage
White paint with Red accents emphasizes the immense Cadillac body, formal roofline, and exaggerated length. A chrome roll cage, oversized rear tires, and modified stance turn the traditionally formal silhouette into something much more aggressive. Inside, Red leather covers six bucket seats with four-point harnesses, creating a striking combination of limousine accommodation and custom-performance equipment.
Driving Experience
The supercharged 454ci V8 and TH400 automatic promise a very different experience from the restrained character normally associated with a Fleetwood-based Cadillac. Wide rear drag tires, the narrowed axle, four-link suspension, and harness-equipped seating define the build’s attitude. Vintage Air conditioning, rear entertainment equipment, and the dry bar preserve a strong luxury element for passengers.
