SBM Hyd. Camshaft

The SBM Hydraulic Camshaft from Howards Racing Components (MPN 710461-10) is a precision-engineered hydraulic flat tappet camshaft designed for small block Mopar applications. This camshaft delivers 0.525-inch intake lift and 0.531-inch exhaust lift across a 273-degree intake duration and 277-degree exhaust duration, with a 110-degree lobe separation angle optimized for street and moderate performance builds.

The 2200–6000 RPM operating range indicates this camshaft excels in engines prioritizing mid-range torque and street responsiveness rather than extreme high-RPM peak power. The hydraulic flat tappet design provides automatic valve clearance compensation through hydraulic lifters, eliminating the manual adjustment requirements of solid tappet systems. This specification set—combining modest lift, extended duration, and a tight lobe separation angle—produces a broad, usable power band suited to cruising applications and moderate weekend performance driving without sacrificing driveability at idle or part throttle.

Small block Mopar builders—whether restoring a vintage Dodge, Plymouth, or Chrysler or upgrading an existing A, B, or RB engine—rely on Howards Racing Components camshafts for their consistent quality and proven performance. This camshaft is ideal for owners seeking improved throttle response and acceleration over stock profiles while maintaining reliable engine operation and compatibility with factory hydraulic lifter systems. Howards' reputation for precision grinding and quality control makes this profile a popular choice for both street and bracket racing applications in the Mopar community.
