SBC Extreme Energy Cam XE274H-10

The SBC Extreme Energy Cam XE274H-10 is a hydraulic flat-tappet camshaft specifically engineered for small block Chevy engines that aim for aggressive naturally aspirated performance. This camshaft is ideal for engine builders and enthusiasts looking to enhance their vehicle's output while maintaining drivability.

Featuring a maximum lift of 0.490 inches on both the intake and exhaust sides, the XE274H-10 camshaft has a 274-degree intake duration and a 286-degree exhaust duration. It operates effectively across a broad 1800–6000 RPM powerband, with a 110-degree lobe separation angle that enhances throttle response and cylinder filling efficiency. The hydraulic flat-tappet design simplifies installation and reduces costs compared to roller systems.

This camshaft is particularly effective in small block Chevy applications, typically ranging from 262 to 400 cubic inches, where mid-range torque is a priority. Engine builders can expect improved performance without sacrificing reliability, making it a great choice for both street and light competition environments.
