Q & A

What's in the Box

Clevite's H-Series was developed primarily for use in NASCAR type racing, but they are suitable for all types of competition engines. These sets are specifically for 1955-1969 265-283-302-327 S/B Chevy "small journal" engine (with 2.000" rod journals).

  • 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.
  • The X001 option gives you .001" extra oil clearance

Clevite P-Series 1955-69 Small Block Chevy Rod Bearings
(Part #757R673)

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 265-283-302-327 S/B Chevy "small journal" engines built from 1955-1969 (with 2.00" 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.
