Product Details

The COMP Cams K11-409-8 Nitrous HP hydraulic roller camshaft K-Kit is engineered specifically for Chevrolet Big Block 396-454 engines running nitrous oxide systems. This complete camshaft package delivers aggressive performance with 224/236 duration specifications optimized for nitrous-assisted applications, providing excellent power gains while maintaining reliable street manners.

Complete K-Kit Includes Everything You Need:

  • Hydraulic roller camshaft with nitrous-optimized lobe profiles
  • Matching hydraulic roller lifters
  • High-performance valve springs designed for increased lift and rpm capability
  • Precision valve spring retainers
  • Valve locks (keepers) for secure valve train operation
  • Valve stem seals to prevent oil consumption
  • Timing chain set for accurate cam timing
  • Assembly lube for proper break-in protection
  • COMP Cams decals and detailed installation instructions

This hydraulic roller design eliminates the need for break-in procedures required by flat tappet cams while delivering superior performance and durability. The Nitrous HP grind is specifically calibrated to work with the rapid cylinder pressure increases generated by nitrous oxide injection, making it an ideal choice for street/strip big block Chevy builds with power-adder systems.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

Did not mention anything about mounting hardware, will cancel sale if no mounting kit, thank you

Great pricing and quick shipping. I'll be using them again for sure.
