Product Details

The COMP Cams Xtreme Energy 23-703-9 is a high-performance solid roller camshaft engineered specifically for Chrysler 383-440 big block engines. With 254/260 duration specifications, this camshaft delivers an aggressive performance profile while maintaining street-friendly driveability characteristics.

Key Features:

  • Accelerated valve opening profile for enhanced throttle response and increased area under the lift curve
  • 254/260 duration specification optimized for Chrysler big block applications
  • Solid roller design for maximum durability and performance consistency
  • Maintains adequate manifold vacuum for power brakes and vacuum-dependent accessories
  • Delivers significant torque and horsepower gains over stock camshafts
  • Compatible with both carbureted and fuel-injected applications

Performance Applications:

  • Ideal for street/strip performance builds and muscle car restorations
  • Works with stock components but achieves best results with performance upgrades
  • Recommended supporting modifications include aftermarket intake manifolds, headers, free-flowing exhaust systems, and lower rear gear ratios

The Xtreme Energy camshaft family represents COMP Cams' commitment to balancing maximum performance with real-world driveability. This camshaft provides the aggressive valve timing needed for substantial power gains while retaining the vacuum signal necessary for daily driving comfort and accessory operation.

best price i could find online. fast shipping

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.
