Product Details

The COMP Cams Xtreme Energy hydraulic roller camshaft is engineered specifically for Chrysler B/RB big block engines (383-440 cubic inch). This performance camshaft features 236/242 duration specifications designed to deliver increased power and torque across a broad RPM range while maintaining excellent street manners and reliability.

Key Features:

  • Hydraulic roller design reduces friction and wear for extended service life
  • 236° intake / 242° exhaust advertised duration for aggressive performance
  • Xtreme Energy profile optimized for street/strip applications
  • Compatible with stock or aftermarket hydraulic roller lifters
  • Improved throttle response and mid-range power delivery
  • Suitable for engines with upgraded valve springs and intake systems

This camshaft is ideal for enthusiasts building performance-oriented big block Chrysler engines who want noticeable power gains without sacrificing driveability. The hydraulic roller design eliminates the need for periodic valve lash adjustments while providing the performance benefits of a roller cam profile. Best results are achieved when paired with appropriate valve springs, lifters, and supporting modifications.

easy pay good prices

Excellent price, quick shipment, and recommended to anyone! They have the cheapest prices on the web! Period!

I ordered online with autoplicity via google checkout. It was easy and a real good price compared to other sites. The communication was great every step of the way. Order confirmation, order tracking number and shipping number. Super fast shipping for a heavy item (springs)and was in perfect condition. I Will shop with them again.

Hands down the best price on the Magnaflow catback I have seen by more than 20%. They were able to work out the ship-from-manufacturer tracking after a quick phone call. Will definately be recommending these guys to others.

Great prices on the products I want. Quick shipping.
