Product Details

The COMP Cams CL11-676-4 Xtreme Energy camshaft and lifter kit is designed for big block Chevrolet engines (396-454 cubic inches) seeking aggressive performance with solid flat tappet valve train technology. This cam delivers a 230/236 degree duration split that provides excellent mid-range to top-end power, making it ideal for street/strip applications, hot street rods, and performance builds that can accommodate higher stall converters and gear ratios.

Key Specifications:

  • Advertised Duration: 280°/286° intake/exhaust
  • Duration at .050": 230°/236° intake/exhaust
  • Valve Lift: .510"/.520" intake/exhaust (with 1.7:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 2,000-6,000 RPM
  • Valve train type: Solid flat tappet

Complete Kit Includes:

  • High-energy solid flat tappet camshaft
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

This camshaft requires periodic valve lash adjustment and works best with aftermarket cylinder heads, headers, and a 2,500+ RPM stall converter. The aggressive profile provides a noticeable lope at idle and strong acceleration characteristics throughout the power band. COMP Cams Xtreme Energy profiles are engineered with advanced lobe design technology to maximize performance while maintaining durability.

Autoplicity did a wonderful job, and was definitely the best price. I don't know how they do it, BUT I'll buy more from them. Amazingly swift delivery. GREAT SERVICE !!!!!!

Ordered a Dee Zee bed mat for my truck. Got it right away and it fits like a glove!!!

Order an item a day ago and the next day its shipped! Had a question and customer service was there when you needed it!

I did a pretty extensive search looking for a good price on a specific set of Autogage gauges. They had the best price and were in stock with quick notification of shipment. Order # 27510 should be here soon so I can finish my project. Would so business with again.
