Fitment Notes

.010" (0.25mm) undersize - for use with crankshafts that have been ground .010" undersize; verify crank journal diameter before ordering
For standard (unground) crankshaft applications, use CB663P (standard size)

Lower bearing halves include dowel holes for compatibility with aluminum connecting rods
Sold as a set of 8 bearings - sufficient for one complete V8 engine build

Features

P-Series Tri-Metal (TM-77) construction - steel backing with copper-lead intermediate layer and electroplated lead-tin-copper overlay
Higher eccentricity and high crush factor engineered to compensate for rod bore distortion at high RPM
Oil grooves extend all the way around both halves for superior oil distribution and film retention
Hardened steel backings with extra-thin overlays to prevent overlay fatigue under high load
Extra-clearance variants available (+0.001") for precision oil clearance tuning
Direct replacement for OEM bearings - suitable upgrade from bi-metal bearings in performance and race applications
Proven in race and high-performance street engines from naturally aspirated to supercharged and turbocharged builds
Made to Clevite's industry-leading quality and dimensional standards since 1948

Product Description

The Clevite CB663P10(8) is a complete 8-piece P-Series connecting rod bearing set for the Chevrolet Small Block V8 (305-400 c.i.) and GM LS V8 engine families, designed for crankshafts that have been ground .010" undersize. The P-Series is the oldest and most versatile member of the Clevite 77 performance bearing family - built on hardened steel backings with a Tri-Metal construction that layers copper-lead alloy beneath an electroplated lead-tin-copper overlay for exceptional load capacity and durability.

Engineered specifically for high-revving applications where rod bore distortion under load is a concern, P-Series bearings feature higher eccentricity and increased crush factor to maintain proper bearing clearance and oil film thickness. Full-circumference oil grooves in both halves promote consistent lubrication, and the lower halves include dowel holes for use with aftermarket aluminum connecting rods. Whether you're rebuilding a street engine, a bracket racer, or a high-boost forced induction build, the CB663P10(8) delivers the performance and reliability Clevite 77 is known for.
