I can see why you would want to investigate this. If you paid an extra "premium" for a car with an advertised 427 FE you should be aware if you didn't get what you paid for. It will also help you to know in the event you decided to sell your car in the future so that you advertise it correctly.

If the car works well and meets your performance expectations by all means enjoy driving it. I've had the opportunity to have 2 similarly equipped ERA Cobras recently. One was a 427 side oiler with dual carbs and the other is a 390 single carb setup. Both are equally enjoyable to drive on the street. Proper building practicies, head, intake, carb selection and TUNING go a LONG way to making either enjoyable so I would place more emphasis on these details for a personal driver than how the factory short block started. Unfortunately, resale value seems to think otherwise these days?
