Product Details

The COMP Cams SK11-318-4 Magnum camshaft kit delivers enhanced performance for Chevrolet Big Block 396-454 engines with a 236°/236° duration profile.

  • Hydraulic lifter set (16 lifters)
  • Timing chain and gear set for proper cam timing
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

Key Specifications:

  • Lobe Separation Angle: 112°

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.

easy site to maneuver, fast checkout!

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.
