The COMP Cams 12-921-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft features a 260/268 duration profile that delivers excellent mid-range to upper RPM power characteristics ideal for circle track competition.

Key Specifications:

  • Advertised Duration: 260° intake / 268° exhaust
  • Camshaft Type: Solid roller (mechanical roller)
  • Application: Oval track racing, circle track
  • Engine Compatibility: Chevrolet small block V8 engines
  • Design: Optimized for sustained high-RPM operation and consistent power delivery

Performance Benefits:

  • Aggressive lift and duration profile for racing applications
  • Solid roller design provides superior valve control and durability under extreme conditions

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

great prices thanks

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.

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

Best Price i could find for some nice foglamps. easily navigable website.
