Product Details

The COMP Cams SK35-512-8 is a complete Xtreme Energy hydraulic roller camshaft kit designed for Ford Windsor 351W engines. This kit delivers aggressive performance with a focus on high RPM power while maintaining street-friendly characteristics. The XE258HR-14 camshaft profile features moderate duration and lift specs optimized for engines with aftermarket cylinder heads, headers, and intake systems.

Key Specifications:

  • Camshaft Duration: 258°/264° advertised, 218°/224° @ .050"
  • Valve Lift: .525"/.540" with 1.6 rocker ratio
  • Lobe Separation Angle: 112°
  • Hydraulic roller design for reduced friction and enhanced durability
  • Power range: 1,500-6,000 RPM
  • Recommended minimum compression ratio: 9.0:1

Complete Kit Includes:

  • Xtreme Energy hydraulic roller camshaft
  • Matching hydraulic roller lifters
  • Assembly lubricant
  • Installation instructions

This kit is ideal for street performance and mild street/strip applications where improved throttle response, mid-range torque, and top-end horsepower are desired. The hydraulic roller design eliminates the need for break-in procedures required with flat tappet cams and provides excellent longevity. Requires aftermarket valve springs (not included) to handle the increased lift and duration.

Very quick and easy. Thanks

The website was not being nice to me , but when I called the on two days I found the sales help wonderful. They were able to help me find what I wanted at a great price... Thanks Autoplicity!!!

Bought a Husky gearbox for my Silverado, great price and a great product. Install was simple and the fit was perfect. Gone are the days of opening the rear door and all the items under the seat sliding out. Great for my hitch, tow straps, jumper cables and other miscellaneous must haves in a truck. Great seller the price was the best on the net even with shipping. Item arrived quick and in perfect shape. Thanks!!

Autoplicity has the cheapest prices around and fast shipping. I will do business with them again in the future.

Great Pricing (lowest i can find anywhere) and Quick Shipping, Product has no damage from shipping! Thank you Autoplicity!

I ordered this Weathertech cargo liner (order#: 8049) on a Tuesday and received it by Saturday. Speedy delivery and absolutely love this product. It is a perfect fit and still easy to get to the storage compartment of my Rav4.
