Product Details

The COMP Cams Xtreme Energy hydraulic roller camshaft is engineered to deliver exceptional performance gains for Chevrolet Big Block Gen VI engines. Featuring a 248/254 duration profile, this camshaft utilizes a quicker valve opening design that increases throttle responsiveness and maximizes the area under the lift curve compared to conventional grinds.

Key Features:

  • Xtreme Energy profile with 248/254 duration for enhanced performance
  • Hydraulic roller design for reduced friction and increased durability
  • Improved torque and horsepower across the powerband
  • Maintains adequate vacuum for power brakes and accessories
  • Preserves street driveability and creature comforts
  • Compatible with Chevrolet Big Block Gen VI engines

Performance Application:

This camshaft is ideal for street/strip applications where performance gains are desired without sacrificing daily driveability. While it works well in carbureted setups, optimal performance is achieved when paired with aftermarket intake manifolds, headers, free-flowing exhaust systems, and lower gear ratios. The Xtreme Energy grind delivers strong mid-range torque while maintaining smooth idle characteristics suitable for street use.

Designed specifically for Big Block Chevrolet Gen VI engines, this hydraulic roller cam provides the perfect balance between performance and practicality for enthusiasts seeking reliable power gains.

Thank you

Awsome A+ I got my order really quick.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.

Easy order placement, fast shipment
