Product Details

The COMP Cams K42-236-4 Magnum/Marine hydraulic flat tappet camshaft kit is engineered for Oldsmobile V8 engines from 260 to 455 cubic inches. This cam delivers 244 degrees of advertised duration on both intake and exhaust, providing a smooth idle with strong mid-range torque and excellent top-end power. The hydraulic flat tappet design offers reliable performance for street, marine, and recreational applications without the maintenance requirements of solid lifters.

Complete K-Kit Includes:

  • Hydraulic flat tappet camshaft with 244°/244° advertised duration
  • Hydraulic lifter set matched to cam profile
  • Performance valve springs designed for increased lift and duration
  • Steel valve spring retainers
  • Valve locks (keepers)
  • Valve stem seals for positive oil control
  • Timing chain set with gears
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

This all-in-one kit provides everything needed for a complete valvetrain upgrade, eliminating the guesswork of component matching. The Magnum series camshaft profile is optimized for engines with stock or mildly modified cylinder heads, providing improved performance while maintaining good vacuum for power brakes and accessories. Ideal for street performance, towing, RV, and marine applications where reliability and broad power delivery are essential.

Fair price for part and shipping.

Easy site to navigate. Ordering process simple.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Very easy

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.
