need help with engine number

[wendell42]

I have a '76 B210, when I got it from a friend, he had just re-built the an A12 engine and put it in the car.  I am not entirely sure what year the engine was, but was told it came out of a 1200 (I guess that narrows it down a BIT).

 

The number stamped on the side of the engine on the tabs is A12 699854  do any of these numbers indicate what year the engine is?  I dont want ot order the wrong part for the engine because I got the year of the engine wrong.

 

Any assistance would be appreciated.

Year not that important as far as parts are concerned. An A12 is an A12. 

[wendell42]

Awesome.  That is a relief.  Thanks for the info.

Just don't get parts specific to an A12a.  71-73 A12 parts are OK.

I thought there were two variants on the A12: an early (1970's) model and a late (1980's) model. The former installed in the 1200's and the latter installed in 210's.

The latter are A12a and are marked as such.

Did the A12A have the distributor up fron too?

[datsunaholic]

A12A had the dist in the same place as the A14/A15, which is to say, no, it was in the middle-rear.  It's based on the 1974 block redesign.  I believe only the original A12 (and the obscure A10) , and not the A13, A14, A15, or A12a had the front distributor.
