Product Details

The COMP Cams 12-430-8 Magnum hydraulic roller camshaft delivers excellent mid-range performance for small block Chevrolet engines. This camshaft features 224/224 degrees of advertised duration and is designed to work with hydraulic roller lifters for reduced friction and improved durability compared to flat tappet designs.

Key Specifications:

  • Advertised Duration: 224°/224° (Intake/Exhaust)
  • Duration @ .050": 196°/196°
  • Valve Lift: .420"/.420" (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 114°
  • RPM Range: 1,000-5,000
  • Hydraulic roller design for reduced friction and maintenance

Performance Benefits:

  • Smooth idle quality with slight lope
  • Strong torque and horsepower gains in the 1,500-4,500 RPM range
  • Excellent street manners with improved throttle response
  • Compatible with factory valve springs and components
  • Works with stock fuel injection and computer systems

This camshaft is ideal for street performance applications, daily drivers, and mild performance builds where drivability and reliability are priorities. The hydraulic roller design eliminates the need for break-in procedures required by flat tappet cams and provides long-lasting performance. Requires hydraulic roller lifters (not included) for proper operation.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

easy

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
