Michigan/Clevite R8400/CB-927P(8) Ford 351 400M Connecting Rod Bearings
Michigan Engine BearingP-Series rod bearings are the oldest members of the Clevite 77 performance bearing family. They're intended for high-revving engines, especially those where the high rpm cause the rod bores to narrow. To compensate for this distortion, these direct replacements have higher eccentricity and a high crush factor. Clevite P-Series rod bearings are built on hardened-steel backings with extra-thin overlays, and their lower sections have dowel holes for use with aluminum rods, and there are extra-clearance variations available with an additional 0.001 in. of clearance.
