Product Details

The COMP Cams 12-211-2 Magnum camshaft delivers a substantial performance upgrade for Chevrolet small block engines, featuring an aggressive 224/224 duration profile on a hydraulic flat tappet design. This camshaft is engineered to provide excellent mid-range to upper RPM power gains, making it ideal for street/strip applications where strong acceleration and top-end performance are priorities.

Key Specifications:

  • Advertised Duration: 268°/268° intake and exhaust
  • Duration at .050": 224°/224° intake and exhaust
  • Valve Lift: .447"/.447" (with 1.5 rocker ratio)
  • Lobe Separation Angle: 110°
  • Recommended RPM Range: 1,600-5,800
  • Hydraulic flat tappet design for reliable street performance

Performance Features:

  • Symmetric duration profile provides smooth, predictable power delivery
  • Tight 110° lobe separation creates strong cylinder pressure and excellent throttle response
  • Moderate lift allows use with factory valve springs in most applications
  • Produces a noticeable performance idle with classic cam lope
  • Requires upgraded valve springs, timing set, and break-in procedures

This camshaft works exceptionally well in 305-400 cubic inch small block Chevy engines with compression ratios of 9.5:1 or higher. Best results are achieved with aftermarket intake manifolds, headers, and free-flowing exhaust systems. The Magnum series represents COMP Cams' most popular performance camshaft line, trusted by engine builders and enthusiasts for over four decades.

Smooth Transaction. Would definitely shop here again.

Yay

Great fast service

Great

Not only was it the cheapest price, but they had the fastest and lowest price shipping, and best customer service. Thanks Autoplicity!

Found the parts I needed for my vehicle's TPMS system that I could not get anywhere else. They were a better price than any of the other online stores and got my order shipped out in a timely fashion.

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

great doing business with you

Great prices, fast shipping.

Good service, fast shipping, excellent prices
