Product Details

The COMP Cams 12-911-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft features aggressive 260/268 duration specifications optimized to deliver strong mid-range to upper RPM power characteristics ideal for circle track competition.

Key Features:

  • Solid roller design for maximum valve control and durability under high-RPM racing conditions
  • 260° intake / 268° exhaust duration (advertised) provides excellent power band for oval track racing
  • Engineered specifically for Chevrolet small block V8 engines (262-400 cubic inches)
  • Oval track grind optimized for sustained high-RPM operation and consistent lap times
  • Requires compatible solid roller lifters, valve springs, and retainers (sold separately)
  • Designed for use with aftermarket cylinder heads and higher compression ratios

This camshaft is intended for dedicated racing applications and requires proper valve train components including solid roller lifters, performance valve springs, and retainers rated for the camshaft's lift and duration specifications. Professional installation and proper break-in procedures are recommended to ensure optimal performance and longevity.

They had the lowest price and great communication. Will order from them again thanks

For as cheap as what I paid for my product I will admit I was scared!!! Got what I asked for in perfect condition, came fast and wonder where have you been all my shopping life? Thanx for such a great deal and fast shipping!!!

great that it linked to amazon. I will be a repeat customer

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Unbeleiveable!!!! Super fast shipping!! Great job!!! Keep up the good work!<br><br>P Savaria

best price, cheap shipping, easy to order, thank you Order Number: 4829<br>
