Edelbrock retrofit hydraulic roller lifters (#97433) are a complete set of 16 designed for 1990-and-earlier Big-Block Chevy Mark IV engines. These precision lifters convert early non-roller blocks originally equipped with conventional lifters to accept hydraulic roller valvetrain components, providing consistent tolerances suitable for higher RPM street and performance use.
