"That thing gotta 273?"

well, no one has ever asked me if that's a 273. i think we're the only ones who know they exist.

Well, they did stop making them FIFTY years ago (as hard as that is for me to believe).

In a similar vein, people have mistaken this for a poly 318, but nope - it's a 277 (factory four barrel and dual exhaust, but the carb and air cleaner are not original). Looks just like a 318 poly, but it's not.
