Product Details

The COMP Cams SK66-236-4 High Energy SK-Kit is a hydraulic flat tappet camshaft package engineered for street performance in Ford 240 and 300 cubic inch inline six-cylinder engines. Featuring the proven 252H grind, this cam is tuned to deliver strong low-end torque, improved fuel efficiency, and crisp throttle response — making it an ideal upgrade for daily drivers, trucks, and performance street builds.

The High Energy camshaft series is specifically designed to work harmoniously with stock components including factory intake manifolds, exhaust manifolds, and carburetors, while improving output across the RPM range. This cam will not negatively affect vacuum-dependent accessories such as power brakes, power steering, or air conditioning.

quick, easy. product not exactly what I wanted but close enough. good value

I did not get a final chance to see the order total with shipping +coupon applied. Order was 105+11.95 shipping -20offshipping-so should have been 96.95, but never saw the final price. The fix for this would be to show the final price before customers click pay. Product and shipping time were as expected.

Nice site. Checked you folks against RockAuto and liked you way better!

I was so happy to find the chrome GMC license plate that my boyfriend has been looking for on this website at a very affordable price! It was easy to find and easy to order. Can't wait to get it in the mail!

Great service, awesome prices, incredibly fast shipping. A++ I would absolutely suggest you to my friends and family
