Product Details

The COMP Cams 11-742-9 is a high-performance drag race solid roller camshaft engineered specifically for Chevrolet Big Block engines (396-454 cubic inches). This aggressive camshaft profile delivers maximum power for competitive drag racing applications where every horsepower counts.

Camshaft Specifications:

  • Advertised Duration: 285°/312° (intake/exhaust)
  • Solid roller design for reduced friction and increased valve control
  • Optimized for drag racing and high-RPM performance
  • Direct replacement for Chevrolet Big Block 396, 402, 427, and 454 engines
  • Requires compatible solid roller lifters, valve springs, and retainers (sold separately)

Performance Characteristics:

  • Aggressive profile designed for maximum power output at high RPM
  • Solid roller construction eliminates hydraulic lifter limitations
  • Ideal for dedicated drag race vehicles with supporting modifications
  • Requires proper valve train components and periodic adjustment

This camshaft is intended for race-only applications and requires supporting modifications including high-performance valve springs, pushrods, rocker arms, and a proper tune. Professional installation and valve train setup are strongly recommended to ensure optimal performance and reliability.

Good website!

very easy

Wow!! I came across Autoplicity while searching for a fuel pump for my Trans-Am. Not only did they have the cheapest price for the part, but they also had extremely reasonable shipping cost. Most websites claim to have free shipping but it seemed the cost of shipping was added to the cost of their part. Then I find out my order was processed and shipped within one business day!! I'll definately be bookmarking Autoplicity's home page!! Thanks!!

Easy ordering

Awesome! Would do business with again.

Excellent prices. Reasonable shipping. Website is a little tweaky but if that keeps prices low who cares!

Site is easy to navigate
