What is the benefit of a 1.6 ratio rocker arm?

A 1.6 ratio rocker arm means that for every amount the camshaft lobe lifts, the rocker arm will open the valve 1.6 times that amount. This can lead to increased valve lift, potentially improving engine response and performance.

Are these rocker arms noisy?

These Hi-Energy rocker arms are designed to eliminate the noise and slop often associated with older, worn stock rocker arms. The needle bearing fulcrum and roller tip also contribute to smoother operation.

What kind of camshafts are these rocker arms compatible with?

These rocker arms are an excellent replacement choice for engine rebuilds using either stock camshafts or COMP Cams High Energy camshafts. They also feature a long slot that can accommodate higher lift camshafts.

Product Details

If you're rebuilding a Ford 351 Windsor engine or dealing with noise from worn-out stock rocker arms, these COMP Cams Hi-Energy rocker arms are a solid choice. They're designed to replace those tired, noisy originals and bring some quiet back to your engine bay. Whether you're sticking with a stock camshaft or stepping up to a High Energy cam, these rockers can handle the lift.

These particular rockers feature a 1.6 ratio, which means they'll open the valves a bit further than stock, potentially improving engine response. They're made from aluminum for a good strength-to-weight ratio and have a needle bearing fulcrum along with a roller tip. This setup helps reduce friction, which in turn can lower oil temperatures and contribute to better performance. They're built tough enough for moderate racing use, making them a versatile option for street and mild race applications across a range of Ford engines.

This set is specifically for pedestal mount applications on Ford 351 Windsor engines, and they fit a wide variety of Ford vehicles from the late 60s through the mid-90s, including trucks and Broncos.
