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:

So, yesterday afternoon, I remembered that I got a file with a ton of receipts, including receipts for the engine rebuild. I also called one of the prior owners (from 2010 to 2013!) and he filled me in on some info. I also have the contact info for the prior owner that rebuilt the engine in 2008, although I haven't called him yet.

The car was originally a 2.0 liter. In 2008, a shop owner bought the car. The body was solid, but the engine was toast. So, he built a new engine from the ground up. Apparently he built it on a 1.7 liter VW Type 4 engine case (I haven't found the receipt for the case yet), but everything else was 2.0 liter. The original heads were sent off for rehab and re-used (I have that receipt). The cylinders and pistons were purchased new. It was converted to dual Weber carbs at that time, and the correct camshaft for carbs was installed. I have all of those receipts (literally 2 inches thick pile of receipts).

So, I think I know the answer to what happened. I guess the only remaining question is why he used a VW Type 4 1.7 liter case to build the engine on. I suppose in 2008 it wasn't that big of a deal to keep numbers matching. And although the car is in nice shape (I'd call it a good solid "3" condition), it's not a concours vehicle. I drive my cars, and this one drives great with good power. So, in the end, if the engine case number shows it wasn't the original, I can live with that. I am happy that I have all of those receipts to document the car's history.

Thanks to all of you guys for the help!
