Crower 66377H-16 Features:
Crower 66377H-16 severe-duty mechanical solid roller lifters for 1962-up Ford 221-302-351W Windsor V8; complete 16-piece set with double offset design. HIPPO high-pressure pin oiling uses EDM-fed oiling from the oil band to the needle bearings for continuous lubrication under extreme high-rpm valvetrain loads. Billet alloy 1-piece lifter bodies are CNC-machined and heat-treated, with cutaway construction, heavy-duty raised blade, and larger thick-wall .750 in. OD bearings. Nominal lifter body OD is .874 in. measured at .8731 in., with 1.730 in. pushrod seat height and approximately 126 g weight per lifter.
