Chevrolet V8 265-400, 396-454. For the enthusiast who chooses a solid lifter cam, COMP Cams® offers the highest quality mechanical lifters available today. These lifters are manufactured using the tightest tolerances in the industry, ensuring optimum performance. The crown of the lifter is ground to a precise radius for proper break-in and to guarantee long life. The oil metering band is milled to the correct depth to prevent too much oil from being delivered to the top of the motor, robbing precious horsepower. Remember, the lifter is the most important component between the cam profile and the valve, so make COMP Cams® Solid Lifters your choice for maximum power and warranty protection.
