European model versus US or ROW rest of world model
there are slight differences such as compression ratio and trim
IIRC it's US or Euro/ROW model.
Your engine case would show a ROW engine code (see the engine nos. at the 914 info link at the top of the page), no side front side markers (& not "shaved" or filled in), no "PORSCHE" on the engine lid grill, VW-Porsche logo badge at the rear panel, probably no VIN label in the driver rear door jamb - since that compliance sticker was only required by DOT on US cars, maybe a few other diffs.
However, lots could've changed by POs on any of the above.
Call PCNA next week during EDT business hours with your VIN, select Customer Care & COA options, & ask for a preliminary check on what their records for VINs show. If you want to get a COA for it, then joining PCA saves you something like $20 - so about half the PCA $42/yr. (plus 2 magazines per year & 20% discounts at dealers a few times per year - worth the toll IMHO).
