The engine was just overhauled a week and a half ago, I installed it with the new overhaul. I want to trade it for a clean Caprice engine, and no one should buy it for cash. Denali 2012 engine, ready, overhauled from top to bottom. Condition: recently overhauled and still in the break-in period, I haven't exceeded 3.5k RPM on it yet. Still in break-in period, I've driven 1000 km, 1000 km remaining.
