S&S CYCLE Cam - 450 Series - Big Twin 33-5064

If you're running a lower-compression Big Twin and looking to unlock reliable torque across the power band, the S&S 450 Series cam delivers proven performance without compromising streetability. S&S backs every cam with hundreds of dyno, street, and racetrack test hours—this isn't a prototype, it's a validated upgrade. The 450 Series excels at building low and mid-range punch, making it ideal for riders who want usable power without the complexity of high-compression builds.

This is a straightforward bolt-in installation for motors running up to 8.5:1 compression, though S&S recommends solid lifters for optimal reliability. As with any cam swap, your installer will need to verify coil bind, valve-to-valve clearance, valve-to-piston clearance, and cam lobe-to-case clearance to ensure safe operation.
