General Motors Clevite 77, Tri-Metal Main Bearing Set fits the following:265 CID 4.3L LS5 Pontiac V8 1980-1981,301 CID 4.9L Pontiac V8 1977-1981,301 CID 4.9L Pontiac Turbocharged V8 1980-1981.Clevite Tri-Metal 77 Main Bearing Set combines the strength of a copper-lead alloy (Bi-Metal) layer with steel backing and an electro-plated Micro Babbitt metal as an overlay. Clevite Main Bearing Set part number: MS1415P10 (0.010in. / 0.25mm Oversize)The steel backing on the Clevite Tri-Metal 77 Main Bearing Set provides strength and durability. The Bi-Metal Babbitt overlay provides the conformability and Load Capacity. The Third layer - Micro-Babbitt overlay provides the critical surface Embedability Conformability and has far more forgiveness than bi-metal. This ideal design has properties not found in many original equipment bearings. In most cases Clevite Tri-Metal 77 Bearings are an upgrade over a stock bearing, or three times better.It takes Three Layers to be Number One, and Clevite 77 Tri-Metal Bearings are it ! Engineering quality engine bearings involves a number of interdependent factors. Here is how Clevite 77s Tri-Metal cast copper lead material compares to bi-metal bearings on the most important of these factors:Seizure Resistance: Tri-Metal bearings have significantly greater seizure resistance than bi-metal bearings, by as much as 40%.Load Capacity: Tri-Metal bearings can withstand much higher loads for longer periods of time as compared to bi-metal bearings, over 60% higher loads.Embeddability Conformability: The overlay on a Tri-Metal bearing offers a far more forgiving surface than bi-metal bearings. This feature may not be as critical during OE assembly as it once was, but it does offer additional protection that can be extremely beneficial in maintaining your engine.Durability: Clevite 77s Tri-Metal bearings not only exceed light vehicle OE durability requirements of 150,000 miles, the
