Product Details

The COMP Cams 12-912-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft features aggressive duration specifications of 264 degrees intake and 268 degrees exhaust, optimized to deliver maximum power in the RPM ranges critical for circle track competition.

Key Specifications:

  • Intake Duration: 264 degrees
  • Exhaust Duration: 268 degrees
  • Solid roller lifter design for maximum stability and valve control at high RPM
  • Engineered specifically for oval track racing demands
  • Compatible with Chevrolet small block V8 engines

Performance Benefits:

  • Delivers strong mid-range to high-RPM power for competitive oval track racing
  • Solid roller design eliminates lifter pump-up at sustained high RPM operation
  • Aggressive profile provides excellent throttle response and acceleration
  • Purpose-built lobe profiles optimized for the repetitive left-turn demands of circle track racing

This camshaft requires solid roller lifters, appropriate valve springs, and related valvetrain components rated for the increased lift and duration specifications. Professional installation and proper break-in procedures are essential for optimal performance and longevity.

Fast & painless other than filling the bank to be able to spend it.

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

This was my first experience ordering from Autoplicity. The ordering process was easy, I got the parts that I wanted at the best price I could find, and they came quickly. I can't ask for more than that.

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.
