What does the 0.060 size mean for these bearings?

The 0.060 size indicates that these bearings are intended for a crankshaft that has been machined down by 0.060 inches. This is a common practice during engine rebuilds to ensure a precise fit on a reconditioned or worn crankshaft.

What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum base. This type of material is well-suited for engine bearing applications, offering good performance and durability.

Are these bearings a direct replacement for all Ford 390 engines?

These bearings are designed for Ford 330, 352, 360, 390, 410, and 428 engines. They are sized 0.060 inch undersize, meaning they are for use with a crankshaft that has been machined to that specification, not necessarily a direct drop-in for every stock engine.

Product Details

This is a King Engine Bearings main bearing set, specifically sized 0.060 inches undersize. You get the main bearings needed to rebuild the bottom end of a Ford 330, 352, 360, 390, 410, or 428 engine. These bearings are constructed with a bimetal aluminum base, which is a common and well-built material for engine bearings.

These bearings are designed to fit a wide range of vehicles from the late 1950s through the mid-1970s, including popular models like the Ford F-100, Ford Fairlane, and Chevrolet Impala. The 0.060 inch undersize means they are intended for crankshafts that have been machined down by 0.060 inches during an engine rebuild. This is a standard practice to ensure a fresh, precise fit on worn or reconditioned crankshafts.
