that's a transplant. The splash 216 ws not known for long life / durability....
This engine had a 216.48-cubic-inch (3.5 L) displacement with a 3.500” (88.90 mm) bore and a 3.750” (95.25 mm) stroke. A four-bearing crankshaft was added, along with 6.5:1 compression pistons, for 85 hp (63 kW). A new cylinder head in 1941 increased output to 90 hp (67 kW), and 6.6:1 compression gave the 1949 model 92 hp (69 kW). This generation did not use a fully pressurized oilingsystem. The connecting rods were oiled using an "oil trough" built into the oil panthat had spray nozzles that squirted a stream of oil at the connecting rods (which were equipped with "dippers"), thus supplying oil to the rod bearings.
Rod bearings were made of babbitt cast integral with the rod. The bearing was adjustable for wear by removing copper shims placed between the rod cap and connecting rod. In this way specified oil clearance could be maintained. If the crankshaft were to be turned undersized, or if the bearing was damaged or worn out, rod and bearing were replaced as a unit, typically at the dealership.
