Cool comes in multiple flavors. One one hand, we have the sophisticated attraction of svelte design and the efficient use of power. Of course, on the other hand there is the allure of being the bad boy and going against the grain. That is part of the appeal of rat rods. Ideally, they are built without rules to an owner's specific tastes, and this widened and heavily modified 1947 Chevrolet pickup rod is a perfect example of that spirit.
