Product Details

The COMP Cams SK11-409-8 Nitrous HP Small Kit is a complete hydraulic roller camshaft package engineered specifically for nitrous oxide applications in Chevrolet Big Block 396-454 engines. This performance camshaft features a 224/236 duration profile optimized to deliver maximum power under nitrous injection while maintaining excellent drivability characteristics.

Key Specifications:

  • Camshaft Duration: 224°/236° (intake/exhaust)
  • Valve Lift: Optimized for nitrous HP applications
  • Camshaft Type: Hydraulic roller
  • Engine Application: Chevrolet Big Block 396-454 cubic inch

Complete SK-Kit Includes:

This Small Kit provides all the essential components needed for a professional camshaft installation, eliminating the guesswork of component matching.

Awesome price! I couldn't find a better bargain anywhere, and I searched for days.

Best price on VP fuel jugs and way fast shipping

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

My experience with autoplicity was great. Great selection and service. Fast shipping. Will definitely use them again.

I loved that you have low shipping cost.

Helpful-reasonable prices-reasonable shipping-prompt.

Lowest prices and fast shipping made this a great transaction.

Good price, quick shipping, no instant refund though!

cheapest price, better than summitt or jegs too

Lowest price usually means sub-par customer service. Not the case at Autoplicity. I had questions after my item shipped, they responded promptly and professionally multiple times, and were totally willing to work with me. Very satisfying, would not hesitate to order from Autoplicity again.
