If it's an original 312 the rear flange of the crankshaft will have a dot on it
and the main bearing caps will have an "ECZ" prefix, not EBU.

Apparently a very few of the 312 crankshafts don't have the dot on the rear flange but most of them do.
Both of the (Cleveland foundry) '57 312 engines in my garage have the dot. (if that means very much)

How to ID a 312, two links....
http://ford-y-block.com/identify312.htm

http://ford-y-block.com/crankshaftid.htm

The 312 crank also has a slightly different overall appearance. Photos at the 2nd link above.
In some cases having ECZ main caps will be more definitive than a potentially missing dot, if you don't have the means to measure the bore & stroke.
That said... it is possible to machine the mains of a 312 crankshaft down to fit into a 292 block and use the stock EBU main caps and rear seal. But it's a very one-off sort of thing.

Yes, people think a 312 is always a 312. I suppose it is, but the 312s were different, as highlighted above. Seems like the draft tube was different, and a water jacket drain was different too. People say 312 to me all the time, but the 312 Thunderbird Special was a different crank, and block all together, as I recall. When true car guys ask about a 312, I think they are asking about the 312 Thunderbird Special. Guess that's just me.

The 292 & 312 blocks and crankshafts used in the '55/'57 T-birds & full-sized Fords of a given year are the same parts.
http://ford-y-block.com/Block%20identification.htm

http://ford-y-block.com/crankshaftid.htm

A full-sized Ford with a Y-block engine could have either a Cleveland or Dearborn cast block. (There were also foundries in Canada and Brazil which were a possibility.)
The '55/'57 T-birds only used blocks cast in Cleveland,

But, there were no blocks or crankshafts used exclusively for the '55/'57 T-Birds.
As a marketing tool the Birds might get engine upgrades sooner but they were also optional on the full-sized cars.

There are several bolt-on pieces that make a complete Thunderbird engine different. Most were just to accommodate the lower & set-back position in a narrower engine compartment with a lower hood.
Rear sump oil pan, timing cover, dual exhaust manifolds, tach drive dist, valley pan, air cleaner, road draft tube ....

Excepting the E and F code versions, the "Thunderbird" option package on a full-sized car was usually a 4bbl carb, dual exhaust, a couple other performance parts and emblems or decals.

Sure it's very possible, why not? no argument here.
When talking about Ford parts and cars there are two words I've learned not to use: always & never.
For anything made in Canada it goes double.

The original post by cvicky didn't specifically mention a crankshaft, only the block number & 2bbl carb.
Since the engine block ID chart on the Mummert website doesn't list the possibility of a CECK block being a 312,
their information could just be out of date.
as is this one...
http://www.yblockguy.com/identify_y-block.htm

Given the relatively low numbers of Canadian vs US engines this wouldn't be surprising.
