COMP Cams short‑travel retro‑fit hydraulic roller lifter for Chevrolet Small Block 265–400 ci is intended for early blocks originally equipped with flat tappet cams. The tall body fits standard blocks and tall lifter‑bore aftermarket blocks; short travel reduces internal piston movement to minimize "pump up," allowing higher RPM capability when correctly installed.
