BBC 320/360 Dart Stud Girdle - 7/16 Studs

The BBC 320/360 Dart Stud Girdle with 7/16 studs is a precision rocker arm support component engineered for Big Block Chevy (BBC) engine builders and high-performance enthusiasts. This stud girdle stabilizes rocker arm geometry and maintains consistent valve train alignment under demanding operating conditions. Whether you're assembling a street performance build, marine engine, or competition platform, this girdle ensures reliable valve actuation and reduces unwanted rocker arm deflection that can compromise engine efficiency and durability.

Constructed from lightweight aluminum and finished in gold anodize for corrosion resistance, the BBC 320/360 Dart Stud Girdle features 7/16-20 thread studs with integrated polylock fasteners that prevent vibration-induced loosening during operation. The gold anodized finish not only protects against oxidation but also aids in heat dissipation around the rocker arm assembly. This design maintains proper rocker arm geometry across the entire RPM range, which is critical for valve timing accuracy and reducing stress on pushrods and valve stems. The precision engineering ensures compatibility with Dart cylinder heads and BBC blocks, delivering the stability needed for aggressive cam profiles and high lift applications.

Rebuilders, engine shops, and serious hot rodders standardize on this Dart girdle for BBC 320 and 360 applications where valve train control directly impacts horsepower delivery and component longevity. Installation is straightforward using the 7/16 studs with standard thread pitch, and the polylock design eliminates the need for secondary locking compounds. Proper torque and installation ensure the girdle maintains its alignment throughout the engine's operational life, protecting your investment in quality cylinder heads and performance components.
