Product Details

The COMP Cams 11-606-5 is a high-performance solid flat tappet camshaft designed specifically for drag racing applications in Chevrolet Big Block engines from 396 to 454 cubic inches. This aggressive grind delivers exceptional top-end power and is ideal for serious bracket racing and competition applications where maximum performance is the priority.

Camshaft Specifications:

  • Duration at 0.050": 256° intake / 264° exhaust
  • Solid flat tappet design for racing durability
  • Optimized for Chevrolet Big Block V8 engines (396, 402, 427, 454 CI)
  • Designed for drag racing and high-RPM competition use
  • Requires compatible valve springs, lifters, and pushrods (sold separately)
  • Intended for manual transmission applications

Performance Characteristics:

  • Aggressive profile delivers strong mid-range to top-end power
  • Broad powerband suited for bracket racing consistency
  • Requires higher stall converter (manual trans recommended)
  • Best suited for engines with upgraded valve train components
  • Rough idle quality—not recommended for street use

This camshaft is designed for dedicated race engines and requires proper valve train components including high-performance valve springs, solid lifters, hardened pushrods, and appropriate valve train geometry. Professional installation and precise valve lash adjustment are essential for optimal performance and engine longevity.

Have only placed order so far - not received product. Order process is standard fare, not good or bad. Why am I being asked to provide feedback before I've recieved anything?

Tried ordering same parts from StockWiseAuto, it was a terrible hassle and i gave up. So far, I'm glad I ordered from Autoplicity instead, no hassle at all.

good prices

Easy process,, reasonable shipping.

Easy to order with PayPal and got the Chevy powder-coated valve covers very fast. Great quality product, too. Thanks!

Great Prices and fast, fast shipping. I will definitely do business with them again.

Great site. Prompt shipment and service
