Product Details

The COMP Cams 10-203-4 Magnum camshaft delivers a significant performance upgrade for AMC V8 engines ranging from 290 to 401 cubic inches. This hydraulic flat tappet camshaft features a symmetrical 224°/224° advertised duration profile designed to provide excellent mid-range torque and strong top-end power without sacrificing street manners.

Key Specifications:

  • Advertised Duration: 224° intake / 224° exhaust
  • Duration at .050": 224° intake / 224° exhaust
  • Valve Lift: .420" intake / .442" exhaust (with 1.6 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic flat tappet design for reliable street performance
  • Compatible with AMC 290, 304, 343, 360, 390, and 401 V8 engines

This cam profile is ideal for street and street/strip applications where strong throttle response and a broad powerband are priorities. The hydraulic design eliminates the need for valve lash adjustments, making it an excellent choice for daily drivers and weekend performance vehicles. Recommended operating range is 1,500-5,500 RPM with peak power typically achieved between 4,500-5,000 RPM.

Installation Notes: Requires compatible hydraulic flat tappet lifters, timing set, and valve springs with appropriate seat pressure and coil bind clearance. Always verify piston-to-valve clearance during installation.

Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

Great Prices and fast, fast shipping. I will definitely do business with them again.

Ordered some fluid coolers for a project, great price, easy website, FAST shipping!

I had never heard of Autoplicity before placing this order. I found Autoplicity via Google and decided I'd give them a try as they were the cheapest option. <br>Autoplicity did have the lowest price. The order was shipped promptly and got to me 2 days after ordering and the next day after it was shipped. I am very happy with this purchasing experience and would purchase from Autoplicity again without any hesistation.<br>
