292 Thunderbird eng??

[F-word541]

I have a 56 Country Sedan wagon with a 292 that came with a Holley 4 barrel carb and dual exhaust. It has the Thunderbird engine logos on the front fenders. I have had a couple people tell me that the logos were put on aftermarket because the thunderbird engine has to be a 312. I have heard from others that there is a 292 Thunderbird engine. Can anyone tell me if my car did in fact come with a 292 Thunderbird engine or did someone stick the logos on after the fact?
