These guys are sitting on the bleeding edge of technology and helping all of us grow the motorsport - they're stories are just fascinating. Randy Reyes joins the guys to talk about his Cummins Dually and what's involved in his engine build. He also describes the work he's done to the transmission with an emphasis on the valve body. Sit back and enjoy - it's another great episode of the Diesel Performance Podcast.
