Product Details

The COMP Cams 11-725-9 is a high-performance solid roller camshaft engineered specifically for drag racing applications in Chevrolet Big Block engines (396-454 cubic inches). This aggressive camshaft delivers exceptional top-end power and acceleration for serious competition use.

Key Specifications:

  • Advertised Duration: 286° intake / 310° exhaust
  • Solid roller design for maximum valve control and high-RPM stability
  • Designed for Chevrolet Big Block engines: 396, 402, 427, and 454 cubic inch displacements
  • Optimized for drag racing and competition applications
  • Requires aftermarket valve springs, lifters, and pushrods (sold separately)
  • Split-pattern design with longer exhaust duration for improved cylinder scavenging

Performance Benefits:

  • Maximizes high-RPM horsepower and torque for quarter-mile performance
  • Solid roller construction eliminates deflection for precise valve timing
  • Aggressive profile delivers strong top-end power band
  • Split-pattern grind optimizes exhaust evacuation for forced induction or naturally aspirated builds

This camshaft is intended for dedicated race engines with appropriate supporting modifications including high-ratio rocker arms, performance valve train components, aftermarket cylinder heads, and a higher stall speed converter. Professional installation and proper valve train setup are required for optimal performance and engine longevity.

Autoplicity was quick and easy to order from. I found just what I was looking for in absolutely no time at all, plus it was shipped extremely quickly. I would definitely order from this site/company again.<br><br>Thanks!

excellent ship time and exceptional pricing deffinatly will buy from here again

Fast shipping, product was excellent .

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.

Smooth transaction, very pleased

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.
