Product Details

The COMP Cams Magnum 11-470-8 hydraulic roller camshaft is engineered specifically for Chevrolet Big Block engines (396-454 cubic inches), delivering a powerful balance of mid-range torque and upper RPM performance. This camshaft features a 252/252 duration profile that provides excellent street manners while offering significant performance gains over stock camshafts.

Key Specifications:

  • Advertised Duration: 252°/252° intake and exhaust
  • Duration at .050": 218°/218° intake and exhaust
  • Valve Lift: .510"/.510" (with 1.7:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic roller design for reduced friction and increased durability
  • Requires compatible hydraulic roller lifters and timing set (sold separately)

Performance Benefits:

  • Smooth idle with mild lope characteristic
  • Strong acceleration and throttle response
  • Optimized for street/strip applications with RPM range of 1,500-5,800
  • Ideal for engines with aftermarket intake, headers, and compression ratios of 9.0:1 or higher
  • Compatible with stock or aftermarket cylinder heads

This Magnum series camshaft is a popular choice for enthusiasts seeking a noticeable performance upgrade without sacrificing daily drivability. The hydraulic roller design eliminates the need for break-in procedures required with flat tappet cams, while providing superior valve train stability and longevity.

The merchandise I found was a good deal.

It said I would get a discount by signing up for the newsletter. That was false. I did find a coupon, but you should remove that from your site if that's not the case. Other than that, exact product I ordered arrived very quickly to my residence. Overall very satisfied with my shopping experience.

Priced perfectly. Great buy!

Got part fast, with no issues

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 so far

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