Product Details

The COMP Cams SK11-675-4 Xtreme Energy camshaft kit is a complete solid flat tappet package designed for Chevrolet Big Block 396-454 engines seeking aggressive performance gains. This kit features the popular 224/230 duration profile that delivers a noticeable increase in mid-range to top-end power with a strong choppy idle.

Great price, great service, A+

Fast shipping, great product. Nothing more needs to be said.

great price and customer service

They had the parts I needed at the best price. I needed some questions answered to make sure I was ordering the right parts for a 4 year old car and they were very helpful when I called.

Best price on the internet for my parts. Shipped out the next morning.

Finding my parts on this website was incredibly easy. The prices were the lowest around and I was kept up to date about the estimated delivery date. Order #19058

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

I ordered a rear sway bar for my MINI Cooper on Sunday and it was at my door on Wednesday! Autoplicity had the absolute cheapest price for this bar and I was very impressed with the shipping speed. I would definitely recommend them to my friends!
