What’s Inside a 15-Liter Cummins Semi-Truck Engine?

Along the way, the guys made their guesses on how much some of these massive parts weigh — including the cylinder head. A full teardown, a few bets, and a look inside one seriously massive Cummins engine. Top products: Hamilton Cams Conversion Kit: https://shop.davesusa.com/collections...
