Edelbrock Rollin Thunder Hydraulic Roller Cam SBC 87-Later

Upgrading camshaft performance in late-model SBC engines improves drivability and power delivery. This Edelbrock Rollin Thunder hydraulic roller camshaft is designed for 1987-later SBC engines from 283 to 400 cubic inches (non-LT1/ non-Gen III), delivering strong low- and mid-range torque with improved throttle response.

Features and Benefits:
- Designed for 1987-later SBC engines 
- Hydraulic roller reduces friction and wear 
- Improves low and mid-range torque output 
- Operates from idle to 5500 RPM range 
- Smooth idle for street applications

The hydraulic roller design reduces friction while providing consistent performance across the operating range. Designed for street-driven vehicles, trucks, and utility applications, it operates from off-idle to 5,500 RPM with smooth idle characteristics. When paired with Performer or Performer RPM intake manifolds, it provides balanced performance for everyday driving and mild performance builds.
