What specific Ford engines are these rocker arms designed for?

These COMP Cams Ultra-Gold ARC rocker arms are designed for Ford 289 and 351 Windsor engines. They are compatible with models from 1977 through 1992 that utilize a 5/16" stud and pedestal mount configuration.

What is the benefit of the 1.6 ratio?

The 1.6 ratio means that for every 1 unit of movement at the pushrod, the rocker arm will move the valve 1.6 units. This increased leverage can help improve valve lift, potentially leading to better airflow and increased engine power.

Does this set include the necessary studs and hardware for installation?

This product is a set of 16 rocker arms and is designed for engines with existing 5/16" studs and pedestal mounts. It does not include the studs or other mounting hardware; those should be sourced separately if needed.

Product Details

Starting with a 1.6 ratio, these COMP Cams Ultra-Gold ARC rocker arms are built to handle up to 700 lbs of pressure, a notable improvement over stock components. They are constructed in the USA after Finite Element Analysis (FEA) to ensure strength and stability where it matters most in your engine. This set of 16 is specifically designed for Ford 289 and 351 Windsor engines from 1977 through 1992 that use a 5/16" stud and pedestal mount.

The Ultra-Gold ARC design helps to improve power output and maintain valve train stability, especially under demanding conditions. COMP Cams has engineered these rockers to be a direct fit for your specified Ford applications, ensuring that installation is as straightforward as possible for a component of this nature. The aluminum construction, combined with the FEA analysis, results in a well-built part that contributes to the overall performance and longevity of your engine.

When rebuilding or upgrading the top end of your Ford 289 or 351 Windsor, these rocker arms are a solid option. They are designed to work with the existing pedestal mount and 5/16" stud configuration, making them a practical choice for many classic Ford builds. Ensure you have the correct 5/16" studs and pedestal mounts for proper installation.
