Unleashing the Power: The 750HP, IRS Chassis 1966 Pontiac 2+2 ‘Survivor Series’

The Roadster Shop presents their latest creation, a remarkable ‘Survivor Series’ build of a 1966 Pontiac 2+2. This stunning vehicle combines vintage aesthetics with modern performance, featuring a powerful 750HP engine and an advanced IRS chassis. Let’s dive into the details of this impressive build.

The Car

This 1966 Pontiac Catalina Survivor underwent a meticulous restoration by the Roadster Shop. Starting with a bone stock 1966 Pontiac 2+2, the team transformed it into a true driving pleasure. The Fast Track independent rear chassis provides stability and superior handling, complemented by 14-inch brakes and Fox RSV 4.0 shocks on all four corners. The car rides exceptionally well, offering a smooth and enjoyable driving experience.

The Engine

Under the hood, the ’66 Pontiac 2+2 packs a Wagner LS3 supercharged engine, generating an astounding 750 horsepower. To enhance its appearance, the team machined a custom blower plate for the Edelbrock Supercharger, giving it a more fitting and appealing look within the Catalina’s engine bay. Despite its incredible power output, the engine remains user-friendly and tamed, making it a pleasure to drive.

The Transmission

Power is delivered to the wheels through a Tilton twin-disc clutch and a T56 six-speed transmission with a long tail shaft, provided by Bowler Transmission. This combination ensures smooth shifts and optimal performance, especially considering the vehicle’s supercharged engine. The transmission upgrade, along with the clutch and throw-out bearing, make the ’66 Pontiac 2+2 an easy-to-drive, high-performance machine.

Suspension and Brakes

The Roadster Shop’s Fast Track independent rear chassis is the backbone of this build. With a nine-inch center section and single adjustable shocks, the car benefits from exceptional stability and control.

The 14-inch brakes on all four corners provide reliable stopping power, ensuring safe and confident handling even under aggressive driving conditions.


The seats, sourced from a Hellcat Charger, offer excellent comfort and adjustability, while the use of early 60s Impala trim adds a touch of chrome elegance. The leather-wrapped contour steering wheel, provided by JK Custom Auto Design, enhances the overall driving experience.


Maintaining the original appearance of the ’66 Pontiac Catalina, the Roadster Shop retained the iconic eight-lug wheels with a drum brake design.

To simplify the process and reduce costs, they collaborated with Jesse Greening at Greening Auto Company to redesign the wheels as a conventional two-piece set. The result is an 18×10 front and 19×12 rear wheel setup that perfectly complements the lowered stance of the Catalina, giving it a striking and unique presence.


The ‘750HP, IRS chassis 1966 Pontiac 2+2 Survivor Series’ build by Roadster Shop is an exceptional example of blending classic aesthetics with modern performance. This meticulously crafted vehicle features a potent supercharged engine, advanced suspension and braking systems, a thoughtfully upgraded interior, and an exterior that retains the car’s original charm. The result is a powerful, comfortable, and visually stunning classic Pontiac that delivers an exhilarating driving experience.
