We don't know who built it but the blown 392 Chrysler is a thing of drag-racing lore. What we do know is that it's 0.060 inch over, sports a Chris Nielsen cam, and Hot Heads headers, roller rockers, rocker covers, and a big-block Chevrolet water-pump adapter. > Among the things that survived the transformation from Pro Street to show truck was this Dana 60 rear axle. Internally it spins a 3.55:1 gear on a limited-slip differential. Externally it's been ground, filled, blocked, and, of course, painted.
