In the latest UNBOXING video, Gale opens up a box containing a part that could very well put the stock Duramax L5P over 1000 horsepower. Inside the FedEx box is a custom cam from the undisputed leaders in cam shaft technology, Comp Cams. The new cam will help the L5P rev higher with the valves open longer allowing for better exhaust flow. In the next episode of Killing A Duramax, Gale will push the stock engine to 900 horsepower with the stock cam. Then he’ll install the new comp cam and go for the big one thousand.
