These bearings are garage sale priced because they have been discontinued.

 

NO WARRANTY, NO RETURNS ON GARAGE SALE ITEMS

 

Notes

  1. We also reccomend ACL P-Series main bearings in situations where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings.

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.

ACL H-Series Rod Bearings Small Block Chevy Large Journal
                        ACL H-Series Duraglide bearings feature a tri-metal design. Fits S/B Chevy 350/400 with Large Journal crankshafts (2.100").
  • 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.

  • 0.015" thick top layer for superior macro particle embedability and conformability
  • 40 Vickers hardness to resist overlay migration and extrusion
  • 450°F heat threshold for superior protection against friction and overheating
