A friend of mine had me go with him to look at a 1954 Monarch Sun Valley. The Car has had an engine swap to a newer 312!
What I was wondering is, did the Canadian cars have the same 256 ci engine that the American Mercury's had or did they have the 239 like the Fords engine as original engines?
What are the engine codes for each engine?

Based on what I have read, the Canadian 54 Fords all had the 255 inch flathead

I have a Canadian printout that I grabbed from someplace on the internet. It specs a code for the 49-54 Mercs as using an engine code on the data plate for the 255 L head engine as one of the following, 9C,OC,1C and OCB.
Interesting that the engine is a 256 in the USA and a 255 in Canada.

A little bit of shrinkage is all. It's COLD up there.

OK thanks I will check with the owner of the car and get the engine codes off the car. I know the 1954 Fords built in Canada had the flat head engine.
Every Mercury and Monarch I have seen had the over head Y block engine, I know the Y block was available in the Canadian Mercury For sure.

The flathead Merc engines, as I remember, had 255. something CI, while the YBlocks had 256. Not much of a difference. The flathead Fords and the Ford Yblocks both were 239.
And as far as I know, as I stated above and by Old Mics, the Canadian Fords and Merc's had the flathead engine, not the Yblock. Possible, I guess, that the Canadian Mercs had the YBlock but I doubt it.

I stand corrected. Must have been just the Fords.

The 54 Canadian Mercury and Monarchs had a Canadian built 256 CID OHV engine. The engines were stamped rj front of engine below drivers side head parting line if I remember correctly.
Engine casting numbers were CEBZ
The 54 Fords and Meteors had the 255 CID flathead engine. The Canadian 54 Meteor and Ford did not have the new ball joint suspension, they had king pins. The 53 Meteors had the 255 flathead engine except Mainline which had the 239 flathead. The 53 Fords all models had the 239 flathead engine.

Thanks for all the good information My buddy did buy the car so now he can start looking for a engine that is a proper match!
He has some real work ahead of him but it should be a real nice car once it is done! The original color of the Monarch was light and dark green metallic in and out.

Personally I would not change out the engine to the 256 OHV unless you are a purest. The 256 engine is very much an engine of its own and parts are hard to find. Water pump different, fuel pump different, not even close to performance of a 312.

That is what I thought to but he is one of those it has to be stock original kind of guy. He has a 1955 Crown Vic and a 1958 Fairlane retractable and on both of them Every thing is absolutely original!

I'm with Marvh on this one.. Too change out the existing supposed 312 (or even if it's a 292) back to a 256 is a poor use of time & money. First of all the engines essentially look the same. And could even be re painted the Monarch colors. 99+% of the public would never know the difference. And as pointed out, some parts for the original version are very hard to obtain & expensive as it was a one year only version. I'm sure it's a nice car, and maybe originality might be nice, .. but it's not a Packard 12 with an obviously wrong engine, it's a Monarch, with basically the same engine..
