Edelbrock Rollin Thunder Hydraulic Roller Cam SBC 265-350 57-86

Upgrading to a hydraulic roller camshaft improves durability and drivability in SBC engines. This Edelbrock Rollin Thunder camshaft is designed for 1957-1986 SBC 265-350 engines, delivering strong low- and mid-range torque with improved throttle response for street-driven applications.

Features and Benefits:
- Fits SBC 265 to 350 engines 
- Hydraulic roller reduces friction and wear 
- Improves low and mid-range torque 
- Operates from idle to 5500 RPM range 
- Smooth idle for street applications

The camshaft operates effectively from off-idle to 5,500 RPM while maintaining smooth idle characteristics. Designed to work with Performer and Performer RPM intake manifolds, it provides consistent performance across the usable RPM range. The hydraulic roller design reduces friction compared to flat-tappet setups, supporting long-term reliability in retrofit applications.
