I believe the 292 block casting numbers for Ford & Merc are the same in a given year, if that engine was an available option. That said... original Y-block engines in a Mercury from '56 to '59 were 312's.
The engine block to bell-housing bolt pattern is the same.

My '55 Ford had a '54 Mercury 256 in it instead of the 292 it was born with.
I put a 292 back in with no mismatch problems except to shorten the flex-plate/crankshaft bolts about 1/8 inch.
Standard transmission input shafts need a pilot bushing in the crank, automatics do not.

'54 was the first year of Y-blocks and Ford made several production changes to the engines during the year. Some '54 engine parts are usually not interchangeable with the '55 and newer versions.
Distributor, carburetor, intake & exhaust manifolds, timing cover and water pump for example...

Get as many of the bolt-on parts with a replacement 292 as you can. Ford did more upgrades in '57 and one that might catch you off guard is the fitting for the water temp sensor. The '57+ versions are smaller and your '54 temp sensor won't fit in the threaded hole without modification.
Without a matching sensor the '54 Temp gauge will not work correctly. Keep the Temp sensor you have if it's working, to reuse in the replacement engine.

Here are a few links to block casting number charts and crankshaft dimensions.

I believe the "6010" digits in the three charts at this link are a typo, should have been 6015.
