S&S CYCLE 514 Series Cam - Big Twin 33-5050

If you're looking to unlock serious mid-range torque and responsiveness in your Big Twin, the S&S Cycle 514 Series Cam delivers where it matters most. This is a cam that's been validated through hundreds of hours of dyno, street, and track testing—no shortcuts, no promises that can't be backed up. Whether you're building a high-performance cruiser or a dedicated race motor, this cam will give you the aggressive power band you're after without sacrificing reliability.

The 514 Series is engineered for motors running 9:1 compression or lower, making it an ideal choice for builders who want real gains without chasing extreme compression ratios. You'll feel the strongest response between 2500 and 5000 rpm, right where you need it for acceleration and sustained pulling power. Pair this with quality hydraulic or solid lifters, and you've got a foundation for serious performance.
