Product Details

The COMP Cams Xtreme Energy 218/224 hydraulic roller camshaft is engineered specifically for OE roller small block Chevrolet applications. This performance camshaft features a quicker valve opening profile that increases responsiveness and provides more area under the lift curve compared to older, slower grinding profiles.

Key Features:

  • 218°/224° advertised duration for enhanced mid-range power
  • Hydraulic roller design works with OE roller lifters
  • Optimized lobe profile delivers increased torque and horsepower
  • Maintains adequate vacuum for power brakes and accessories
  • Excellent street performance without sacrificing driveability
  • Compatible with stock or aftermarket valve springs

The Xtreme Energy grind family is designed to boost performance while preserving creature comforts and daily driveability. This camshaft works effectively in carbureted applications and delivers optimal results when paired with aftermarket intake manifolds, headers, free-flowing exhaust systems, and lower gear ratios. Ideal for street performance builds seeking a noticeable power increase without harsh idle or drivability compromises.

I highly recommend Autoplicity for any of your vehicle needs. They have some of the lowest prices on the web and super fast shipping, I absolutely will be shopping here for all my future auto needs.

Good product, fast shipping, ease of shopping.

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.

Ordered some special Axles which required Factory shipping. Order was processed efficiently, and axles were shipped from factory in 2 work days. Excellent service, good followup on the order. Definitely a good source for parts.
