What's in the Box
Not to be confused with standard "passenger" car bearings, Clevite's P-Series is their oldest line of premium high performance bearings. These sets are specifically for 400 c.i. Small Block Chevy V-8 engines (1970-1980).
- Use P-Series rod bearings where extremely high RPM’s cause severe rod bore close-in.
- Use P-Series main bearings where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings.
