The 440 CID V8 Commando engine has had some upgrades including a new high-volume oil pump, 5 quart oil pan, new valves and valve guides, a 750 Edelbrock 4-barrel carburetor (original carb comes with the vehicle), new water pump and housing and a Pertronix ignition for a factory look but more reliable spark. The steering column has been rebuilt and a new Mopar battery has been installed.
