Product Details

The COMP Cams 12-996-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This aggressive cam delivers exceptional power and torque characteristics optimized for the demands of circle track competition.

Key Specifications:

  • Advertised Duration: 276° intake / 284° exhaust
  • Solid roller design for maximum performance and durability
  • Optimized lobe profiles for oval track racing applications
  • Engineered specifically for Chevrolet small block engines (262-400 cubic inches)
  • Requires solid roller lifters, performance valve springs, and retainers (sold separately)
  • Professional installation and proper break-in procedures recommended

Performance Characteristics:

  • Split-duration design with longer exhaust duration for improved cylinder scavenging
  • Delivers strong mid-range to upper RPM power band ideal for oval track conditions
  • Excellent throttle response and acceleration off the corners
  • Designed to work with oval track compression ratios and cylinder head combinations

This camshaft is intended for dedicated racing engines and requires supporting modifications including proper valve train components, performance valve springs with correct seat pressures, quality pushrods, and rocker arms rated for solid roller applications. A complete valve train upgrade is essential for reliability and performance. Not legal for street use or emissions-controlled vehicles.

Autoplicity has had the lowest prices as long as I've discovered them a few months ago. They have excellent customer service and ship orders very quickly. I definitely recommend them for all of your auto parts needs.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Now problem with Autoplicity---you contact them---they respond--Thanks

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
