Engine Number - I'm Stumped, 2.0 liter with a 1.7 liter code Options

[FRUNKenstein]

I have a '75 2.0 liter 914. VIN is 4752909774. I was looking for the engine block serial number, and found it in the location for a 2.0 engine. However, based on what I am seeing, the serial number is showing for a 1.7 liter block as it starts with "EA". But then the number doesn't really match up with the charts showing the engine block numbers for 1.7 liter engines because all of the EA serial numbers I see listed online start with "00" after the EA. And also, the engine serial number is in the correct location for a 2.0 liter block. So, I'm stumped.

The other unusual thing is that the last digit appears to be a 0, but it seems smaller than the other numbers. The serial number looks to be EA0152330. But again, the 0 on the end looks smaller, like maybe it really isn't part of the serial number. Any help to shed some light on what this means is greatly appreciated! Here is a pic:

OK, on searching around the internet, I saw a Pelican forums discussion about the engine serial number charts having 7 digits but the numbers actually stamped into the engines omit the first "0" that's shown in the charts. So, that would make my engine serial number fall into the correct range for a 1972 1.7L engine block. (IMG:style_emoticons/default/mad.gif)

I know from seeing for sale ads for the car from long ago that are still on the internet that the engine was rebuilt at some point prior to 2013, dual Weber carbs were added along with the proper camshaft. So, I suppose they could have used a 1.7 L engine for that rebuild. But, that still doesn't explain the location of the engine serial number stamp. When I get home tonight, I will check the 1.7 L serial number location to see if it is stamped there also. If so, then I guess someone might simply have added a second stamping in the normal 2.0 L location.
