Product Details

The COMP Cams Xtreme Energy camshaft delivers enhanced performance for Small Block Chevrolet engines with a 250/256 duration profile and hydraulic flat tappet design. Featuring a quicker valve opening rate, this camshaft profile provides increased throttle responsiveness and more area under the lift curve compared to older, slower-ramping grinds.

Key Features:

  • 250/256 duration specification optimized for street/strip performance
  • Hydraulic flat tappet design for reliable, low-maintenance operation
  • Quick-opening valve profile maximizes torque and horsepower gains
  • Maintains adequate vacuum for power brakes and accessories
  • Excellent driveability characteristics with improved performance
  • Nitride heat treatment for enhanced durability and wear resistance

The Xtreme Energy grind family is engineered to increase performance without sacrificing driveability and creature comforts. This camshaft works effectively in carbureted applications, but achieves optimal performance when paired with aftermarket intake manifolds, lower gear ratios, headers, and free-flowing exhaust systems. An ideal upgrade for enthusiasts seeking noticeable power gains while retaining street-friendly manners.

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

Quick and easy

Best price I could find after hours of searching, I recommend 100%!!!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.
