2. A Vision Realized

CadZZilla’s transformation was nothing short of spectacular. Its metamorphosis began with a 1948 Cadillac Series 62 Sedanette, which served as the foundation for Boyd Coddington’s vision.

3. Striking Features

Every inch of CadZZilla was meticulously crafted to perfection. Its top was chopped to achieve a sleek and aggressive profile, while the hood and front fenders were skillfully sectioned and combined into a remarkable tilt nose. The headlights and taillights were expertly frenched, seamlessly integrated into the car’s distinctive lines. The front bumper boasted high-mounted dagmars, flanking a captivating Moon tank in the grille opening. Under the hood, a powerful 500 cu in (8 l) Cadillac V8 engine with custom-built Holley fuel injection roared to life, delivering unparalleled performance. The rear fins proudly showcased frenched late-model Cadillac taillights, while the exhaust pipes made a bold statement as they elegantly exited through the rear bumper.

4. Performance and Handling

CadZZilla wasn’t just about looks; it was engineered for exhilarating performance. Equipped with a Currie 9-inch rear axle and Koni coil-over springs, the car handled with precision and agility. The steering box, sourced from a 1985 Corvette, provided a responsive and engaging driving experience. To complete the package, Coddington designed a set of 22-inch billet aluminum wheels that perfectly complemented the car’s stunning aesthetics.

5. Unleashing the Purple Beast

To match its awe-inspiring design, CadZZilla received a vibrant deep purple finish from House of Color. This bold choice of color further accentuated the car’s personality, turning heads wherever it went. Whether cruising down the open road or commanding attention at car shows, CadZZilla exuded an undeniable aura of power and sophistication.
