The A10 Engine was designed for the original Datsun Sunny -- the B10 Datsun 1000. 998 cc with small carburetor and 3 main bearings. The A10 Engine was released in September 1966 in the 1967 model year Datsun 1000. The A10 featured a three main bearing crankshaft. Bore was 73mm and stroke was 59mm (same as the older Nissan C engine). With a 2-barrel Hitachi carburetor and an 8.5 to 1 compression ratio this engine produced 62bhp (46kW) @6000rpm and 61.5 lb.ft of torque (83 Nm). The Datsun 1000 Coupe introduced in Sept 1968 was equipped with an uprated A10 engine boasting a free flow dual-outlet exhaust manifold with increased compression ratio, now 9.0:1. With a revised carburetor, this Coupe engine produced 66hp (49kW). Later versions of A10 produced 59 hp (SAE).

Indentification

A10s are easily identified by the 'Datsun 1000' valve cover.

The most distinctive feature may be the rocker cover -- it actually has the engine size on it unlike any other A-series cover.

A more reliable way to identify it -- since the cover may be changed -- is to look for the 'A10' stamp engine ID & serial number

A10 Engine, left side. Most notable feature is lack of a breather pipe hole at the back of the block. The A10 used an old fashion road-breather instead. In fact the entire case bulge is missing in this area.
