The XR270RF-HR is a hydraulic roller design, which offers several benefits over traditional flat tappet cams. Hydraulic roller cams reduce friction, resulting in less engine heat and longer camshaft life. They also offer more consistent valve lift and timing, which can improve engine efficiency and power delivery.
This particular camshaft features a 270-degree duration at 0.050-inch lift (hence the "XR270"), which is a good balance between low-end torque and high-end horsepower. The lift is rated at 0.507-inch at the intake valve and 0.525-inch at the exhaust valve, which helps provide better air/fuel mixture and exhaust flow, respectively.
The XR270RF-HR is designed for high-performance applications, and it is recommended for use with a performance intake, heads, and ignition system. It is also recommended to use a higher-octane fuel to maximize its potential.
In summary, the XR270RF-HR Comp Cams 35-421-8 hydraulic roller camshaft is a high-performance upgrade for your 1969 or 1970 Ford Mustang 351W engine. It offers improved horsepower, torque, and engine efficiency, and it is recommended for use with a performance intake, heads, and ignition system.
