SBF 351C Xtreme Hyd. Cam XE274H

The SBF 351C Xtreme Hyd. Cam XE274H from COMP CAMS is a hydraulic roller camshaft designed specifically for small-block Ford 351C engines that require enhanced street and strip performance. This camshaft is ideal for builders looking for aggressive valve timing and lift while maintaining drivability on pump gas. Whether you're constructing a restomod, a weekend warrior, or a competition-grade engine, the XE274H provides the necessary valve control and efficiency to elevate your powerplant.

The XE274H camshaft features hydraulic roller technology that minimizes friction losses and ensures consistent valve actuation across the RPM range, which is crucial for reliability under high-performance conditions. Its precision-ground lobes are tailored for the 351C's port and combustion chamber geometry, optimizing scavenging and intake charge velocity while avoiding valve-to-piston clearance issues. This design enhances rocker-arm life by distributing loads across a rolling contact surface, making it suitable for both track use and extended street cruising.

The SBF 351C Xtreme Hyd. Cam XE274H is the perfect choice for 351C block owners building carbureted or naturally aspirated engines targeting 450–550 hp. It pairs well with stock or upgraded valvetrain components and requires standard pushrod lengths and rocker arms designed for hydraulic roller applications. Proper installation involves checking cam bearing clearance and following a break-in procedure to ensure optimal performance.
