Details
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 for 1970-1980 S/B Chevy 400 c.i. V-8 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.
- The X001 option has .001" more bearing/oil clearance
- If you aren't sure which type of performance bearing to start with, the H-Series will be your best choice.
