Product Details

The COMP Cams K11-560-4 Nitrous HP Hydraulic Flat Tappet Camshaft Complete Kit is specifically engineered for Chevrolet Big Block 396-454 cubic inch engines running nitrous oxide systems. This camshaft features unique intake lobes that allow engine cylinders to fill better for more complete combustion, maximizing power output when paired with a 125+ hp nitrous kit.

Key Specifications:

  • Camshaft Type: Hydraulic Flat Tappet
  • Advertised Duration: 268° Intake / 286° Exhaust
  • Duration @ .050": 224° Intake / 236° Exhaust
  • Valve Lift: 0.515" Intake / 0.547" Exhaust
  • Lobe Separation: 113 degrees
  • RPM Range: 2000-6500
  • Timing Chain: Double non-roller

Complete K-Kit Includes:

  • Camshaft (cast iron)
  • Hydraulic flat tappet lifters
  • Performance valve springs, retainers, and locks
  • Valve stem seals
  • Timing chain set with 3-bolt cam gear
  • Assembly lubricant
  • Installation instructions and decals

The Nitrous HP line features a wider lobe separation and added exhaust duration to help shift and spread the power band for better traction and power under the curve. This cam is designed for street machines with 125+ hp nitrous systems and requires a 2000+ RPM stall converter, 3.73 or lower gear ratio, and will produce a choppy idle. Best suited for street/strip applications where maximum nitrous performance is the priority.

The price as well as the turn time for receiving my product was great. I placed an order late Sunday evening and I have received my order by Wednesday of that week. I still can't get over how great the price was for the bike rack I ordered compared to all of the other sites out there.

Lowest price and S&H around! Prompt responses! Will def buy from again!

yes experience.

The best deal on the same parts that everyone else has. Saved me $75 from the best price any 'Seller" had on the "bay". Will be back. A+ service.

It took a day or two for them to ship my order, but it arrived quickly once shipped. The price was by far the best available.
