@blazinbiddlesoffroad: Testing the '83 turbo diesel K5 on California's state rock 🔥 Serpentine — some of the slickest rock you'll ever try to climb, took four-low to get up it. Just working the 6.2 turbo diesel and letting that turbo spool. All part of dialing this K5 into the perfect off-road machine 💪 #squarebody #k5blazer #turbodiesel #rockcrawling #blazinbiddles
