Product Details

The COMP Cams SK11-550-5 Magnum Marine camshaft kit is a complete small kit (SK-Kit) designed specifically for Chevrolet big block engines (396-454 cubic inches). This solid flat tappet camshaft delivers 235 degrees of intake duration and 242 degrees of exhaust duration, providing a strong mid-range power band ideal for marine applications where reliability and consistent torque are critical.

  • Timing chain and gear set
  • Assembly lube for proper break-in
  • Installation instructions

Engineered for marine environments, this camshaft profile is optimized for low-end and mid-range torque delivery, making it perfect for inboard and stern drive applications. The solid flat tappet design provides durability and consistent valve timing under demanding marine conditions. This kit includes everything needed for a complete cam swap except pushrods and valve springs, which should be selected based on your specific engine build.

Specifications:

  • Intake Duration: 235 degrees
  • Exhaust Duration: 242 degrees
  • Valve Lift: 0.550 inches (based on MPN designation)

I had not shopped at Autoplicity before this purchase. Everything worked out great - product was delivered very quickly and exactly what I ordered. Thank you Autoplicity.

I was very impressed at the timely fashion our order was shipped. I will be shopping with Autoplicity in the future.

great service. Been looking for this trounce product for over a year. best hand cleaner i have ever used. makes the orange stuf seem like using just water.

I ordered my K&N cold air intake order number 17133<br>From autoplicity for almost half price compared to other sites online. I will continue my purchases here n stop my searches elsewhere. And delivery time is fast!

Great Price! Fast Shipping!

Order was correct and came quicker than I expected, I will definitely use Autoplicity again.

Quick and efficient, Thank You!

The ordering process went really smoothly. Got my ordering info e-mailed smartly and was able to track the order easily. Looking forward to using my item as soon as it gets here!

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!
