Holy tube cluster, Batman! The Pro-2 jungle gym gains strength by using strategic tube placement instead of sheer mass and bulk. Behind the cluster, a pair of PWR radiators chills the high-horse Leon Patton 400 small-block. Evan's truck doesn't have a windshield or back window, and air can readily blow right through. This yields the dual benefits of lower wind resistance and better cooling. Evan notes that, "Most of the time, we're not going fast enough on the tight tracks for wind resistance to be a big part of it. At Bark River, though, we can reach 100 mph, and I have a big advantage there over the guys who have a back window. The window acts like a big parachute and slows them down. I hold the fast lap record at Bark River, and I'm the winningest driver at that track."
