Product Details

The COMP Cams 12-940-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This aggressive cam profile delivers exceptional mid-range to high RPM power, making it ideal for circle track competition where consistent power delivery is critical.

Key Specifications:

  • Duration: 260° intake / 264° exhaust (advertised duration)
  • Camshaft Type: Solid roller
  • Application: Oval track racing
  • Engine Family: Chevrolet small block (262-400 cubic inch)
  • Requires solid roller lifters and proper valvetrain components

Performance Characteristics:

  • Optimized for sustained high RPM operation typical in oval track racing
  • Aggressive profile provides strong mid-range torque and top-end horsepower
  • Solid roller design eliminates lifter pump-up at high RPM
  • Designed to work with aftermarket cylinder heads and higher compression ratios

This camshaft requires proper valve spring selection, quality pushrods, and appropriate valvetrain geometry to achieve optimal performance and reliability. Professional installation and break-in procedures are recommended for solid roller camshafts. Compatible with small journal and large journal Chevrolet small block engines when used with correct timing set.

I put my order at 7/29 and received nothing after the order. I emailed to ask my order status at 7/31 and at 8/1 I received my order. Pretty fast shipping. I am satisfied with the shipping and hope later tonight the product will work fine for my car!

product just as described, received in 3 days

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 prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.

Great prices... easy Web interface
