Clevite P-Series 1969-Up Small Block Chevy Main Bearings
                        

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 302-305-327-350 S/B Chevy "Large Journal" engines built from 1969-Up (with 2.100" rod journal).

  • 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.

Note: Will not work with 400 c.i. V-8.
