Product Details

The COMP Cams 12-843-14 is a specialized solid roller camshaft designed for open wheel modified racing applications with traction control systems. This performance camshaft features a unique 4/7 cylinder swap configuration specifically engineered to optimize traction control performance in Small Block Chevy engines.

Key Specifications:

  • Duration: 268°/273° advertised
  • Solid roller design for maximum valve control and high RPM stability
  • 4/7 cylinder swap configuration for traction control optimization
  • Engineered specifically for open wheel modified racing applications
  • Designed for Small Block Chevy engines

This camshaft's unique cylinder swap pattern alters the firing order to create intentional power variation between cylinders, which helps drivers modulate rear wheel traction on dirt and asphalt tracks. The solid roller design provides superior durability and valve train stability under the extreme conditions of modified racing. This cam requires appropriate valve train components including solid roller lifters, heavy-duty pushrods, and proper valve springs to handle the aggressive profile.

Note: This is a specialized racing camshaft intended for competition use only. Professional installation and proper valve train setup are essential for optimal performance and reliability.

Excellent service and fast shipping. A seller I would do business with again.

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Very fast response to order. Only place I could find the product I wanted.

Hands down the best price anywhere. Seamless, hassle free shopping with fast status updates- Bookmark this into your favorites!

Really impressed with prices! Took two weeks to get everything but worth for money I have saved.
