Clevite 1969-Up Chevy H Series Rod Bearings Large Journal-Standard
(Part #757R663H-STD)
                        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 1969-Up 302-305-327-350 S/B Chevy "Large Journal" engine (with 2.100" rod  journals).
  • 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.
  • X001 has .001" extra bearing clearance
