Product Details

This complete kit delivers a performance upgrade with 246° intake and 256° exhaust duration, providing improved throttle response and power delivery optimized for marine environments.

Key Features:

  • Hydraulic flat tappet camshaft design for reliable, low-maintenance operation
  • 246° intake / 256° exhaust advertised duration for broad powerband
  • Marine-specific grind optimized for propeller loads and marine duty cycles
  • Complete kit includes camshaft, hydraulic lifters, assembly lube, installation instructions, and COMP Cams decals
  • Engineered for small block Chevrolet marine engines
  • Xtreme Marine series designed to withstand harsh marine operating conditions

FIRST TIME BUYER SEEMS OK / RECEIVED PRODUCT A OK !!!!

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Great customer service, item shipped quickly. Very satisfied.

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.
