Product Details

The COMP Cams 12-850-9 is a high-performance solid roller camshaft specifically designed for oval track racing applications in Chevrolet small block engines. This aggressive camshaft delivers exceptional power and torque characteristics optimized for the demanding conditions of circle track competition.

Camshaft Specifications:

  • Advertised Duration: 261° intake / 268° exhaust
  • Valve design: Solid roller lifter
  • Application: Oval track racing
  • Engine platform: Chevrolet small block V8
  • Professional-grade racing component

This solid roller cam profile provides the aggressive valve timing and lift characteristics needed for maximum horsepower in racing environments. The asymmetric duration split between intake and exhaust is tuned to optimize exhaust scavenging and power delivery for the specific demands of oval track racing where sustained high-RPM operation is critical.

Important Note: Solid roller camshafts require compatible solid roller lifters, appropriate valve springs, and precise installation. Professional installation and proper break-in procedures are strongly recommended for racing camshafts.

First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

The ordering process was very simple and the prices could not be beat. The processing time to ship the order was a little longer than usual, but for the price savings, it was well worth it!

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Great customer service, item shipped quickly. Very satisfied.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
