Q & A

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 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.

Clevite Engine Parts SH-1349S-STD H-Series S/B Chevy Cam Bearings
                        Clevite's H-Series was developed primarily for use in NASCAR type racing, but  they are suitable for all types of competition engines. 
  • Use H-series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range.
  • H-Series bearings should be used if contact patterns obtained with P-series parts are too narrow. Contact pattern should ideally cover 2/3 to 3/4 of the bearing surface.
  • If you aren't sure which type of performance bearing to start with, the H-Series will be your best choice.
