Product Details

The COMP Cams 12-861-9 is a high-performance solid roller camshaft specifically engineered for oval track racing applications in Chevrolet small block engines. This camshaft features aggressive 259/268 duration specifications designed to deliver maximum power in the critical RPM ranges demanded by circle track competition.

Key Features:

  • Solid roller design for maximum valve control and high-RPM stability
  • 259° intake / 268° exhaust advertised duration for broad power band
  • Optimized lobe profiles for oval track racing applications
  • Precision-ground from premium quality materials for extended durability
  • Compatible with Chevrolet small block V8 engines (262-400 cubic inches)
  • Requires compatible solid roller lifters, pushrods, and valve springs (sold separately)

This camshaft is designed for dedicated racing engines and requires proper valve train components including high-pressure valve springs, solid roller lifters, and hardened pushrods. The aggressive profile makes this cam ideal for oval track engines operating in the 5,000-7,500 RPM range. Professional installation and proper valve train setup are essential for optimal performance and engine longevity.

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 !

Easy order placement, fast shipment

I got a great price on the struts I needed for my car. The price quote I recieved from Goodyear was outrageous in price. Autoplicity made ordering my struts easy and affordable and for a graduate student, I needed to save the money.
