SB Mopar Extreme Energy Cam CRSXE262H-10

The SB Mopar Extreme Energy Cam CRSXE262H-10 by Comp Cams is engineered for serious small-block Mopar enthusiasts seeking measurable horsepower and torque gains without sacrificing streetability. This hydraulic roller cam delivers aggressive valve timing and lift characteristics that maximize airflow through the cylinder head during both intake and exhaust cycles. Whether you're building a weekend cruiser, a track-focused 340, 360, or other small-block Mopar engine, this cam provides the mechanical foundation for reliable power across a usable RPM range that suits both highway and strip applications.

Comp Cams' Extreme Energy line represents decades of valve train engineering optimized specifically for Mopar small-blocks. The hydraulic roller design reduces friction and wear compared to flat-tappet designs while allowing higher valve lift and faster ramp rates that modern engine builders demand. The precisely ground lobes control valve events with tight tolerances, ensuring consistent cylinder-to-cylinder performance and repeatability across multiple ignition cycles. This cam's profile balances aggressive lift with controlled acceleration curves, minimizing valve spring stress while maximizing port fill efficiency—critical for naturally aspirated Mopar builds where every degree of crankshaft rotation matters.

This cam is ideal for small-block Mopar engine rebuilds, performance upgrades, and restorations targeting 340–375 horsepower ranges with stock or mildly modified heads and induction systems. Installation requires a compatible hydraulic roller lifter set, quality pushrods, and proper valve spring rates matched to the cam's lift and duration specifications—consultation with Comp Cams technical support or an experienced Mopar machine shop is recommended before purchase. The SB Mopar Extreme Energy Cam CRSXE262H-10 pairs well with dual-plane intake manifolds, four-barrel carburetors, or EFI systems and works effectively in both muscle car restorations and modern performance applications seeking authentic Mopar character with contemporary reliability.
