Product Details

The COMP Cams SK35-421-8 Xtreme Energy camshaft kit is a complete small kit (SK-KIT) designed specifically for Ford 351 Windsor engines. This hydraulic roller cam features 218/224 duration specs, providing an excellent balance of increased performance and drivability for street and mild performance applications.

Complete Kit Includes:

  • Xtreme Energy hydraulic roller camshaft with 218/224 duration profile
  • Hydraulic roller lifters engineered for reduced friction and wear
  • Timing chain set for proper cam-to-crank synchronization
  • Assembly lube to ensure proper break-in protection
  • Installation instructions and COMP Cams decals

The Xtreme Energy camshaft line is engineered to deliver noticeable power gains throughout the RPM range while maintaining smooth idle characteristics and reliable street manners. The hydraulic roller design reduces valvetrain friction compared to flat tappet cams, improving efficiency and longevity. This kit provides all the essential components needed for a complete camshaft upgrade on your Ford 351W small block engine.

Hopefully these two components work with each other...

Easy to use, and good price.

This was my first purchase from Autoplicity, I bought a HyperTech tuner for my truck, they had absolutely the lowest price of anywhere I looked by far. Only thing I could fault them on is that it took 3 days for the product to ship, a little bit long I feel for something that was in stock, but Ill overlook it since it was such a great price.

Good prices fast delivery

good

I ordered the Dee Zee truck box rails and the price was the best on the net after searching. Also, fast shipping. I would recomend this site.

So far, so good. Right part, fit perfect. What's else can a man ask?
