Cam Bearings
American-made bearings for
new or used blocks have the
surface characteristics of bab-
bitt and will withstand high valve
spring pressures. Use stan-
dard-performance bearings with
hydraulic or solid lifter cams or high-performance bearings with roller cams. Most are available with fluoropolymer composite coating for oil retention and less friction; some are available in .010", .020", .030", and .040" oversizes. Specify size when ordering.
