Clevite 400 Chevy P Series Large Journal Rod Bearing, Standard
SKU-757R324-STD
                        

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. S/B Chevy V-8 engines (1970-1980).

  • Use P-Series rod bearings where extremely high RPM’s cause severe rod bore close-in.
  • Large Journal
  • Use P-Series main bearings where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings.
