Product Details

The COMP Cams 11-744-9 is a high-performance solid roller camshaft specifically engineered for marine applications with Chevrolet Big Block engines (396-454 cubic inches). This camshaft features an aggressive 260/270 duration profile designed to deliver strong mid-range torque and top-end horsepower in demanding marine environments.

Key Features:

  • Solid roller design for maximum durability and performance in marine conditions
  • 260°/270° advertised duration provides excellent power band characteristics
  • Optimized lobe profiles for Chevrolet Big Block 396-454 engines
  • Marine-specific grind engineered for reliability under continuous load
  • Precision ground on state-of-the-art CNC equipment for consistent quality
  • Requires solid roller lifters, matching valve springs, and retainers (sold separately)

This camshaft is ideal for marine performance builds where reliability meets power. The solid roller design eliminates the hydraulic system, reducing potential failure points in marine environments while providing precise valve control. COMP Cams manufactures this camshaft using premium materials and advanced metallurgy to withstand the rigors of saltwater exposure and continuous high-RPM operation.

Note: Professional installation recommended. Proper break-in procedures must be followed. Camshaft requires compatible valve train components including solid roller lifters, pushrods, valve springs, and retainers matched to the cam specifications.

product just as described, received in 3 days

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Your website is great, but I only made this transaction because you cancelled my last one. I tried to order the Deezee brand box and your inventory was off. Hopefully I'll get this one, I really need my toolbox! Update- got the new box, it's just as ad

quick and easy

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
