Phillip Waddell is known to be a man with a bigger plan for his diesel truck. Not long ago, Waddell took his 2007 Dodge Cummins from an average stock and outfitted it with enough power to make a grown man cry. This time, he decided to bring a little life back into his 1977 Suburban. Like his Dodge, the Suburban came to Waddell stock, but didn't stay that way for more than a day. He started swapping out the old engine with a 12-valve Cummins and pouring performance into the `77 Suburban the day it rolled into his garage. Waddell turned it from an unassuming old-school driver into a 537 horsepower street racer.
