Product Details

The COMP Cams K18-420-8 Magnum hydraulic roller camshaft K-Kit is engineered specifically for Chevrolet 262 cubic inch (4.3L) V6 engines. This comprehensive performance camshaft package delivers improved throttle response, increased power throughout the RPM range, and enhanced durability compared to stock flat tappet configurations.

Camshaft Specifications:

  • Advertised Duration: 268°/268° (intake/exhaust)
  • Duration @ .050": 215°/215°
  • Valve Lift: .420"/.420" (with 1.5:1 rocker ratio)
  • Lobe Separation Angle: 110°
  • Hydraulic roller lifter design for reduced friction and increased reliability

Complete K-Kit Includes:

  • Hydraulic roller camshaft with precision-ground lobes
  • Hydraulic roller lifters (16 pieces)
  • High-performance valve springs matched to cam profile
  • Heavy-duty valve spring retainers
  • Valve locks (keepers)
  • Valve stem seals for positive oil control
  • Timing chain set with gears
  • Assembly lubricant
  • Installation instructions and COMP Cams decals

This camshaft profile is ideal for street/strip applications and works well in engines with stock or mildly modified compression ratios. The hydraulic roller design eliminates the need for break-in procedures required with flat tappet camshafts. Recommended for use with 1,500-5,500 RPM operating range and stock or aftermarket fuel injection systems.

Note: Professional installation recommended. Verify pushrod length and piston-to-valve clearance before installation.

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.

quick & easy

Easy shopping

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

Reasonable prices, item shipped quickly, easy to navigate site. Shipping prices were a bit high for my liking though.

Ordered Thursday, shipped Monday... guess all in all we can't be disappointed. At least they had them in stock.
