The badges on the side say Datsun 1200, and a badge below that says 60hp, or 55ps on the Japanese domestic models. The badge on the bonnet says Datsun in an arc at the top and has a capital D in the middle. The bonnet badge on the Bluebird sedan is similar but instead of a capital D it has a sort of boomerang shape logo.
Most 1963 model 320s have the E-1 "Mark 2" engines, which are stamped with engine numbers from 152700 to 280169. These use a bypass type lubrication system, the oil filter housing is cast into the engine block and the filter faces downwards. Camshaft oil pump/distributor drive cog has 10 teeth. The tappet/valve cover is held down by two large nuts on the to of the cover. The oil cap has a wire conecting it to the tappet/valve cover.
Later 1963 models have the E-1 Mark 3 engines with engine numbers from 280170 to 547143. These use a full-flow type lubrication system with a detachable alloy oil filter housing. The oil filter now faces upwards. Camshaft oil pump/distributor drive cog has 13 teeth. 6 Philips head screws hold down the tappet/valve cover. The rest of the vehicle remained largely unchanged from the original 1962 model.
The 1963 model Datsun 320 was in production until August 1963, when it was replaced with the slightly updated 1964 model 320.
