What is the CT-1 coating on these bearings?

The CT-1 coating is a dry film lubricant applied to the bearing surface. It helps to reduce friction and wear, particularly during engine break-in and under high-performance operating conditions.

Are these bearings suitable for a stock engine rebuild?

While these are well-built bearings, they are specifically marketed as 'race' main bearings and feature a performance coating. They are best suited for performance or modified 351 Cleveland engines where increased loads are expected.

Do I need to machine my crankshaft to use these bearings?

No, these are standard size bearings. They are intended for use with a crankshaft that is within factory specifications or has been machined back to standard size. Always check your crankshaft journal dimensions before installation.

Product Details

If you're building a performance Ford 351 Cleveland engine, these ACL race main bearings are a solid choice for the bottom end. They're designed to handle the increased loads and stresses that come with a performance build, helping to keep your crankshaft supported and running smoothly. ACL has been making engine bearings for a long time, and these are well-built for demanding applications.

These bearings feature ACL's CT-1 coating, which is a dry film lubricant that helps reduce friction and wear, especially during the critical break-in period and under high-performance conditions. They are standard size, meaning they're meant to be used with a crankshaft that hasn't been machined undersize. Proper installation is key here; make sure your crankshaft journals are clean and within factory tolerances before installing these bearings.

This set fits a wide range of Ford and Mercury vehicles from the late 60s and early 70s, including popular models like the Mustang, Torino, Cougar, and Montego, as well as the DeTomaso Pantera. Ensure your 351 Cleveland block is ready for a performance rebuild, and these ACL bearings will be a critical component in its foundation.
