The ’65 Ford Mustang with a NASCAR transmission and a 363 stroker engine making 680 horsepower is a true street-legal racecar that combines classic style with modern performance. This article will take you through the fascinating journey of Ron, the owner of this exceptional Mustang, and explore the modifications and features that make it stand out on both the street and the track.

The Story of Ron’s ’65 Ford Mustang

Ron’s journey with his ’65 Ford Mustang began 15 years ago when he acquired a gutted and empty six-cylinder coupe. Instead of going for the popular Fastback version, Ron chose the coupe to avoid butchering a rare and collectible car. His decision to customize a less desirable variant showcased his respect for automotive history and enthusiasts who value authenticity.

Building the Mustang

Ron initially intended to build a street version of the Mustang, but he quickly became immersed in making modifications. Among the notable additions was a roll cage, which not only improved safety but also provided a distinctive visual allure. Although Ron was initially hesitant about installing a roll cage, he eventually recognized the advantages it offered in terms of weight distribution.

The suspension system also received considerable attention, with Ron choosing to incorporate factory Mustang suspension arms.

Ron’s initial plan was to create a street version of the Mustang, but he soon found himself getting carried away with modifications. One significant addition was a roll cage, which not only enhanced safety but also offered a unique visual appeal. Initially resistant to the idea of a roll cage, Ron eventually agreed due to the weight distribution benefits it provided.

The suspension system received attention as well, with Ron opting for factory Mustang suspension arms in the front and a custom-built rear suspension setup. The rear axle was upgraded to a stronger unit to handle the increased power and torque of the engine.

One interesting choice Ron made was to stick with drum brakes instead of upgrading to disc brakes. While disc brakes offer superior stopping power, Ron decided to go with drum brakes for the weight advantage they provided. This decision was based on his goal of creating a lightweight and nimble racecar.

Power and Performance

At the heart of Ron’s Mustang is a 363 stroker engine built by QMP, a renowned engine builder specializing in high-performance applications. The engine produces an impressive 680 horsepower and is designed to deliver exceptional power and torque throughout the rev range. With the help of skilled builders at QMP, Ron ensured that the engine was built to withstand the demands of racing while maintaining reliability.

To harness the power of the engine and provide optimal handling, the suspension system was equipped with high-quality shock absorbers. These shock absorbers not only improved ride quality but also offered adjustability to fine-tune the car’s handling characteristics based on track conditions.

Weight reduction played a crucial role in the overall performance of the Mustang. Ron incorporated lightweight components wherever possible, including a fiberglass hood, lightweight racing seats, and lightweight wheels. By shedding unnecessary weight, the Mustang became more responsive and agile on the track.

Exterior and Interior Modifications

Ron’s attention to detail extended to the exterior and interior of the Mustang. One notable modification was the removal of the drip rail molding, giving the car a cleaner and sleeker appearance. In terms of windows, Ron opted for Lexan, a lightweight and shatter-resistant material commonly used in racing applications. The use of Lexan not only reduced weight but also improved visibility for the driver.

Mounting the Lexan windows presented a challenge, as they required custom brackets and proper sealing to ensure a secure fit. Ron worked closely with skilled fabricators to address these challenges and achieve a professional and functional result.

Inside the cabin, Ron customized the pedal box and installed an adjustable steering wheel, allowing for optimal ergonomics and comfort during spirited driving. The clutch and shift system were also carefully designed to provide a precise and engaging driving experience.

Aerodynamics and bodywork modifications were not overlooked. Ron incorporated a front spoiler and rear wing to improve downforce and stability at high speeds. These modifications not only enhanced the car’s performance but also added to its aggressive and race-inspired aesthetic.


Ron’s ’65 Ford Mustang with a NASCAR transmission and a 363 stroker engine making 680 horsepower is a remarkable street-legal racecar that combines the best of classic and modern automotive engineering. With its aggressive appearance, powerful engine, and exceptional handling, the Mustang is a testament to Ron’s passion, knowledge, and dedication to building a high-performance machine. Whether tearing up the track or cruising the streets, Ron’s Mustang is a true automotive gem that embodies the spirit of racing and the iconic Mustang heritage.
