While at the RPM show in Indy last week, some of the Pro Street racers found some more HP in "Rock Hard Ram" for Van Haisley. Jeff Garmon said, "It's always a pleasure helping fellow dieselheads find horsepower they didn't know they had. " "It was really too easy, but if it helps him win, it's cool," drawled Darren Morrison, DHRA's defending Pro Street Champion.
