Product Details

The COMP Cams 11-405-5 is a high-performance solid flat tappet camshaft specifically engineered for forced induction applications in Chevrolet Big Block engines (396-454 cubic inches). This camshaft features a 255/266 duration split designed to optimize performance with blower and turbo setups.

Key Features:

  • Advertised Duration: 255° intake / 266° exhaust
  • Solid flat tappet design for maximum durability and performance
  • Optimized lobe profiles for forced induction applications
  • Compatible with Chevrolet Big Block 396-454 engines
  • Designed to work with blowers, superchargers, and turbochargers
  • Provides excellent low-end torque and mid-range power under boost

This camshaft is ideal for street/strip applications running forced induction, delivering strong performance across the RPM range while maintaining good drivability. The duration split helps manage exhaust backpressure common in turbocharged applications while maximizing cylinder filling with boosted intake charge. Requires solid flat tappet lifters, appropriate valve springs, and proper break-in procedure.

Quick Service and great pricing!

Fast shipping and the lowest price. Very impressed.

I have looked for this product many times but was disappointed<br>in the price. could not beleive the price at Autoplicity. thank <br>you very much keep up good work Ray

I ordered the HuskyLiners 98891 Floor Liners for my 2012 Hyundai Elantra on 5/29, received them 5/31. Order #15417. Apparently they have warehouses all over the country to ensure quick delivery. They had the best price on the net. Item arrived in perfect condition. <br><br>Their website needs a little work because I found the item thru Google and not directly from their website. You also can't edit your cart unless you register first which was annoying. Items could use product descriptions - you have to get info from the manufacturer's site. The real-time inventory was a plus.<br><br>Deducted a star because their website needs work.

Great Experience and Awesome website. Affordable price as well

We looked a lot of places online for the steering stabilizer for our vehicle. We priced and looked to find out who had the best product and fastest shipping. We were so glad that Autoplicity was able to have just what we needed. We highly recommend that you visit autopicity.com for all you vehicle needs and we thank Autoplicity for their expediency in getting us our stabilizer.

Good prices, fast shipping, A+

After checking amazon, ebay, various other general and specialty online parts suppliers and local brick and mortar supply houses, Autoplicity's was hands down the best overall (price + shipping) price for the product.

Best price I could find on the web and great easy to use website. Fast shipping, I am overall very satisfied thanks Autoplocity!
