The Ford Racing hydraulic roller camshaft for small-block V8s (.498 in. lift) is built for EFI systems with mass-air induction and must be paired with upgraded valve springs rated for higher seat and open pressures. This camshaft provides larger valve lift for performance builds and should be installed with matching valvetrain components to meet the specified spring requirements.
