Product Details

The COMP Cams Magnum 11-208-3 is a hydraulic flat tappet camshaft designed specifically for Chevrolet Big Block engines, including 396, 402, 427, and 454 cubic inch displacements. This camshaft delivers a balanced combination of idle quality, torque, and horsepower, making it an excellent choice for street performance applications and mild street/strip builds.

Key Specifications:

  • Advertised Duration: 280°/280° intake/exhaust
  • Duration at .050": 230°/230° intake/exhaust
  • Valve Lift (with 1.7 ratio rockers): .480"/.480" intake/exhaust
  • Lobe Separation Angle: 110°
  • Camshaft Type: Hydraulic flat tappet
  • RPM Range: 1,500-5,500 RPM

Performance Characteristics:

  • Produces a smooth idle with mild lope for excellent street manners
  • Strong mid-range torque delivery for improved throttle response
  • Optimized for engines with stock to mildly modified cylinder heads
  • Works well with stock torque converters (2,000-2,400 stall recommended)
  • Compatible with stock valve springs and retainers

This camshaft requires hydraulic flat tappet lifters (sold separately) and is ideal for daily drivers, towing applications, and street rods where reliability and drivability are priorities. COMP Cams recommends using their break-in lubricant and following proper camshaft break-in procedures for optimal performance and longevity.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Super easy to browse web site and find the product I wanted.<br>The price was unmatched.<br>Shipping was fast and cheap.<br>Super shopping experience.

Best prices on the net! They had everything I needed at one site.

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Excellent service with the actual stock on hand, shipment was made the next day and a tracking number was provided. I have tried 2 other online supply stores which don't know what they have in stock.
