Product Details

The COMP Cams Xtreme Energy CL12-250-3 is a complete hydraulic flat tappet camshaft and lifter kit designed for Chevrolet small block engines.

  • Duration at .050": 240°/246° intake/exhaust
  • Valve Lift: .477"/.480" intake/exhaust (with 1.5 rocker ratio)

This Xtreme Energy series cam is ideal for street performance applications and muscle car restorations seeking a noticeable improvement over stock performance. The cam works well with stock or aftermarket cylinder heads, intake manifolds, and requires a minimum 9.0:1 compression ratio for optimal performance. Compatible with stock torque converter and rear end gearing, though a 2,000-2,400 RPM stall converter is recommended for best results.

Went well overall. I hope these fit my truck which are larger than the generic applications that fit 25 other vehicles except my truck. Every application I have received so far are about 2/3eds the size they should be for a truck application. Hope I won't
