Details

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.

I've been building engines with these bearings for years. For street and mild performance applications they're great! Copper, lead, tin bearings may be old school but they're much more tolerant of minor dirt and abuse than a lot of the new tech stuff. Keep the build clean, clearances in spec and these will live a long, long time!
