Product Details

The COMP Cams 12-862-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft features aggressive 261/270 duration specifications optimized for maximum power output in circle track competition.

Key Features:

  • Solid roller design for maximum valve control and durability under high-RPM racing conditions
  • 261/270 duration profile delivers strong mid-range to top-end power for oval track applications
  • Engineered specifically for Chevrolet small block engines (262-400 cubic inch)
  • Requires solid roller lifters, matching valve springs, and retainers (sold separately)
  • Designed for engines with aftermarket cylinder heads and performance valve train components
  • Ideal for dirt track, asphalt oval track, and circle track racing applications

This camshaft is part of COMP Cams' extensive oval track racing lineup and is designed to work with high-performance valve train systems. Professional installation and proper engine preparation are required, including degreeing the camshaft and ensuring proper clearances. This cam requires a higher stall torque converter and performance-matched valvetrain components for optimal performance.

product just as described, received in 3 days

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.

Easy so far first time buyer
