Solid Lifters - Chevy w/Coolface Oiling

Crower designed these 66900X980-16 Cool Face Mechanical Flat Tappet Lifters for Chevy V8 engines. They feature a small-diameter .024 in. oil metering port, precision machined in the face of the lifter. This provides direct oiling, resulting in significantly longer camshaft and lifter life with no loss of oil pressure. With today's high-rpm, high rocker arm ratio and high valve spring pressures, cam and lifter failure is at an all-time high. Install these Cool Face lifters for maximum reliability! New lifters must be used when installing a new camshaft to avoid premature lobe and lifter wear.
