Just an FYI, picked up latest issue of Mopar Now and they picked up a used 5.7 too see how far the bottom end can go before it poofs. It was a used core engine with 55k on it that they opened original ring gaps, put in cam, fresh heads etc. It made 1100hp with original pistons,rods,bearings,crank and rings before it ran out of turbo with a safe tune.
