BBF Rocker Arm 1.7 Ratio 7/16 Stud

The COMP CAMS BBF Rocker Arm 1.7 Ratio 7/16 Stud is a full-roller rocker arm engineered for high-performance big block Ford, Ford Cleveland, and modified engine builds. This component is essential for serious engine builders and street or race car enthusiasts seeking to maximize valve lift and improve overall engine responsiveness. The 1.7:1 ratio multiplies camshaft lift, allowing smaller cam profiles to produce equivalent valve motion while reducing valvetrain inertia and wear—a critical advantage in both naturally aspirated and forced-induction applications.

Manufactured from chromoly steel, this rocker arm features a full-roller design that significantly reduces friction between the rocker tip and pushrod interface, translating to improved efficiency and reduced heat generation under sustained high-RPM operation. The 7/16-inch stud mount provides a secure, proven fastening solution that maintains preload consistency across engine cycles. The 1.7 ratio sits in the sweet spot for most big block Ford applications—aggressive enough to enhance power delivery and throttle response, yet manageable for stock and lightly modified bottom ends. The compact dimensions (2.85 x 1.75 x 4 inches) and modest 0.56-pound weight ensure minimal impact on overall engine mass while maintaining structural rigidity.

Engine builders, performance mechanics, and dedicated enthusiasts preparing big block Ford or Cleveland heads for competition, street performance, or restoration with modern upgrades will find this rocker arm indispensable. Installation requires proper pushrod length verification and valve lash adjustment to ensure optimal geometry and prevent interference. The chromoly construction withstands extended high-load scenarios typical of supercharged or turbocharged builds, making it a reliable choice for long-term reliability. Each rocker arm is sold individually, allowing builders to source complete sets tailored to their specific valvetrain configuration and performance targets.
