What is the benefit of bearings made without flash plating?

When should I use Clevite H-Series bearings?

H-Series bearings are recommended for use with crankshafts that have oversize fillets. They are also best suited for engines that are expected to run in the medium to high RPM range, indicating a performance-oriented build.

What is the construction of these main bearings?

About this part

Product Details

Clevite is known for making solid engine components, and their H-Series bearings are a popular choice when you're rebuilding a performance V8. This main bearing set is specifically made for Chevy 400 cubic inch V8 engines from 1970 through 1980, fitting a wide range of vehicles like the Chevrolet Impala, GMC K1500, and Pontiac Grand Prix.

These H-Series bearings feature a medium level of eccentricity and high crush, which helps them seat well in the block. They're built without flash plating, allowing for better contact with the crankshaft. The hardened steel back and thin overlay construction are suited for engines that will see medium to high RPM ranges, making them a good option for performance builds where the engine will be pushed a bit harder.
