I'm new to Datsuns so please forgive my ignorance.
I recently saw an a12 engine with the distributor mounted up the front below number 1 plug. I own 3 engines, all with it back under number 3. Can anyone give me some history on this and is there any performance advantage with this engine over the more common ones I have?
As WE know it the front mount distributor is the 1200 engine and the mid mount distributor is the 120Y engine.
They also need different engine mounts for each as the mount position changes. If for example you are to use the 120Y engine in a 1200 you will need to fabricate new mounts.
There is a difference in the camshaft in the number of gears so a 1200 cam cannot be used in the 120Y engine etc. We had a cam grinder grind a cam that he had sitting in his old cams shelf which he said would fit our engine (we did not see it beforehand) and it was the wrong one of course.
The parts lists show all parts such as bearings and rings etc as common between the two engines.
The larger engines such as 14 and 15 have similar configurations to the 120Y engine
