545rwhp 1976 Gen II Camaro: Robbie Butler's Pro Touring Beast | Full Build Breakdown (2026)

The story of Robbie Butler's 1976 Gen II Camaro is a testament to the power of transformation and the thrill of the automotive world. This car, a true masterpiece, has evolved from a simple right-hand drive conversion to a formidable pro tourer, showcasing the potential for customization and performance. Butler's journey with this iconic muscle car began in 2009, and his vision was clear: to create a machine that would turn heads and dominate the drag strips. Over the years, he meticulously crafted a beast under the hood, pushing the boundaries of what a 1976 Camaro can achieve.

What makes this build particularly remarkable is the attention to detail and the blend of classic aesthetics with modern performance. The engine, a 462ci Dart small-block Chev, is a powerhouse, boasting a 9.5in deck, Lunati stroker crank, Ross pistons, and BME alloy rods. It's topped off with Comp Cams and AFR heads, delivering an impressive 545rwhp on a chassis dyno. The fuel delivery system, a 1000cfm carb with 11.7:1 compression, ensures a healthy inhale, while the 98-octane fuel provides the necessary octane to unleash the full potential of this beast. The TCI 4L80E transmission, with its 5300rpm stall converter, and the Ford 9in diff with 4.11:1 gears provide the necessary torque to handle the power, while the Strange high-torque 31-spline axles ensure stability and control.

The chassis is a work of art, featuring Detroit Speed tubular control arms and subframe connectors, and CalTracs traction bars. This setup not only enhances the car's performance but also provides a solid foundation for the driver to work with. The brakes, Wilwood ventilated discs all around, ensure that stopping power is not compromised, even with the added performance.

The exterior remains true to its original beauty, with the Dodge Viper red respray and white stripes, a testament to the preservation of its classic good looks. Inside, the all-new leather interior by Evans Trim Shop in Toowoomba adds a touch of luxury, creating a contrast between the raw power of the engine and the refined comfort of the cabin. The American Racing wheels, wrapped in 215/40 and 305/30 rubber, provide a sleek and aggressive look, complementing the overall aesthetic.

The results of this transformation are impressive, with a best time of 10.29 at the drags. However, Butler acknowledges the need for a rollcage to push the limits further. This car is not just a weekend cruiser; it's a testament to the art of automotive engineering and the thrill of customization. It showcases the potential for a classic muscle car to become a modern performance machine, all while retaining its timeless appeal.

This build is a reminder that sometimes, the most rewarding projects are those that blend the past and the present, creating something that is both a tribute to automotive history and a cutting-edge performance machine. It's a true labor of love, and the result is a car that not only turns heads but also leaves a lasting impression on anyone who experiences its power and elegance.
