Product Details

The COMP Cams 12-905-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This camshaft features an aggressive 272/274 duration profile engineered to deliver maximum power in the mid-to-upper RPM range where oval track engines operate most efficiently.

Key Specifications:

  • Intake Duration: 272 degrees
  • Exhaust Duration: 274 degrees
  • Camshaft Type: Solid roller
  • Application: Chevrolet small block V8 engines
  • Intended Use: Oval track racing

Performance Features:

  • Solid roller design eliminates lifter flex for precise valve control at high RPM
  • Aggressive duration profile optimizes power delivery for sustained high-speed operation
  • Split duration design (272/274) helps balance cylinder scavenging and power output
  • Purpose-built grind profile for the unique demands of oval track competition

This camshaft requires matching solid roller lifters, appropriate valve springs, and proper engine setup to achieve optimal performance. Designed for dedicated race engines with supporting modifications including aftermarket cylinder heads, intake manifolds, and exhaust systems. Professional installation and proper break-in procedures are essential for longevity and peak performance.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

great experience, good price, item arrived within 4 days of purchase, would do business with again in future !

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.

Easy order placement, fast shipment
