Product Details

The COMP Cams 10-211-4 Magnum camshaft is a hydraulic flat tappet performance cam designed specifically for AMC V8 engines displacing 290 to 401 cubic inches. This cam features a 253/253 duration profile that delivers a strong mid-range power band with excellent throttle response, making it ideal for street performance and mild towing applications.

Key Specifications:

  • Advertised Duration: 253°/253° (intake/exhaust)
  • Camshaft Type: Hydraulic flat tappet
  • Performance Range: 1,500-5,500 RPM
  • Application: AMC 290, 304, 343, 360, 390, and 401 V8 engines
  • Lobe Separation Angle: Optimized for street performance

Features & Benefits:

  • Provides noticeable power gains over stock camshaft
  • Maintains good vacuum for power brakes and accessories
  • Smooth idle quality suitable for daily driving
  • Works with stock torque converter and rear gear ratios
  • Direct replacement for factory hydraulic flat tappet cams

This Magnum series camshaft is designed to work with stock cylinder heads, intake manifolds, and exhaust systems, though performance gains will be enhanced with complementary upgrades. The hydraulic design eliminates the need for valve lash adjustment, making it a maintenance-free performance upgrade. Compatible with all AMC V8 engines from 1966-1991 including those found in Jeep CJ, Cherokee, Wagoneer, and classic AMC muscle cars.

Autoplicity had the lowest price by far and shipping was very fast (ordered Wednesday evening, arrived Saturday morning). I will definitely order from Autoplicity again!

Very pleasant order over the phone. Gentleman was smart, cheerful and helpful.

Thanks

Just what you want from a merchant but don't expect; fast, courteous service and attention to the details of your order. I'm a happy consumer. Thank you, Autoplicity. I'll be back.

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Good products with low prices. Easy website and pament options.

Exact product as promised with the best price on the internet. Product shipped fast and had a tracking number to keep me up to date on my order. I would order from again without hesitation and will tell friends.
