A13 (1974) - the First Tall-Deck A Engine. The 1974 A13 is a 1288cc engine with new tall-deck block casting.
Overview
H62 designed for B210 1974 North America
The 1974 A13 has a 73mm bore like the A10 and A12 before it, but with stroke increased to 77mm for a total of 1288cc. It was used in the 1974 USA B210, and was a tall-deck engine that proceeded the A14 by one year. This one-year-only engine was designed for the American market, to keep the same relative performance with new B210 which was considerably heavier than the B110 (2000 vs 1640 lbs). Compression ratio was 8.5:1 to help meet US emission control standards (same as 1972-1973 USA 1200s at 68hp), yet the A13's increased displacment resulted in 75hp. To accomodate the longer stroke, the 1974 A13 features a "tall-block" casting with a deck height 15 mm (0.59 inch) higher than previous A-series engines.
Applications: * 1974 Datsun B210 (USA and Canada)
Applications
1974 Datsun B210 (USA and Canada) 75 HP @ 6000 RPM
HLB210 H = highline engine L - Left hand drive
It was the highline engine compared to the base B210 -- which was not offered in North America where A13 was the only engine available for 1974. In Japan however the A12 was still used in the B210.
Horsepower
75 HP @ 6000 RPM (SAE), in increase of 10% compared to A12 (68hp)
Along with the increased capacity (more CCs) -- which alone makes more HP at lower engine speeds, the cylinder head and ports were opened up for extra top-end HP (6000 rpm).
