Product Details

The COMP Cams 12-655-5 is a high-performance solid flat tappet camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft features aggressive duration specifications of 260 degrees on the intake side and 262 degrees on the exhaust side, delivering excellent mid-range to upper RPM power for competitive circle track racing.

Key Features:

  • Solid flat tappet design for maximum valvetrain stability and durability in racing applications
  • 260/262 degree duration optimized for oval track racing power characteristics
  • Engineered specifically for Chevrolet small block V8 engines (262-400 cubic inches)
  • Produces strong mid-range torque and upper RPM horsepower for competitive racing
  • Requires performance valve springs, retainers, and pushrods (sold separately)
  • Must be used with solid/mechanical lifters and adjustable valvetrain components

This camshaft is ideal for dedicated oval track racing engines where rules require solid flat tappet camshafts. Proper break-in procedures with ZDDP-fortified oil and assembly lube are critical for flat tappet camshaft longevity. Professional installation and valvetrain setup recommended for optimal performance and reliability.

Ordering was easy, lets see if they can ship it out in a timely manner

Easy and smooth experience

Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

Product was the cheapest I could find. One other store was cheaper but did not have my product in stock. Autoplicity shipped within 2 days and the product arrived as described. I am happy with my purchase and would do business with Autoplicity again. The only thing I marked them on was that I wish they shipped within 1 day instead of 2.

Great Prices and fast, fast shipping. I will definitely do business with them again.
