Product Details

The COMP Cams K11-773-8 Xtreme Energy camshaft kit delivers serious performance for Chevrolet big block 396-454 engines. This solid roller cam features aggressive 254/260 duration timing designed to maximize horsepower and torque in high-performance street and race applications.

Complete K-Kit Includes Everything You Need:

  • Xtreme Energy solid roller camshaft with 254/260 duration specifications
  • High-performance solid roller lifters
  • Premium valve springs engineered for solid roller cam profiles
  • Precision-machined steel retainers
  • Hardened valve locks for secure retention
  • Valve stem seals to prevent oil consumption
  • Heavy-duty timing chain set for accurate cam timing
  • Assembly lube for proper break-in
  • Installation instructions and decals

This solid roller camshaft design eliminates the sliding friction of flat tappet cams, allowing for more aggressive lobe profiles and increased valve lift. The Xtreme Energy series is ideal for engines with upgraded valvetrain components, higher compression ratios, and performance cylinder heads. Recommended for applications with 9.5:1+ compression, performance intake manifolds, and headers.

Specifications: 254/260 duration, solid roller design, compatible with Chevrolet big block 396-454 cubic inch V8 engines including 396, 402, 427, and 454 variants.

First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

They were Very quick and i was very happy with the service i got!! 9-10*

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

This is my second order with Autoplicity. Very happy for a second time!

Good place to shop, fast responce and great prices comapared anywhere.

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Great customer service, item shipped quickly. Very satisfied.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
