Another Engine ID'ing....

[thrashingcows]

I recently picked up a rebuilt flatty 6 to replace the broken one in old Fernando (48 Desoto).

I was reading one of the other posts and I got to thinking that I didn't check the numbers on my new motor to see what I actually have. The motor was pulled from a 47 Plymouth that the fellow had owned 30+ years.

So here are the numbers off the block.... D49 2 5977 C

So I did some research myself and found that this is a motor from a 54 Dodge. And I believe that the "C" at the end designates it a Canadian 25" motor.

So what Cu.in motor might this be? I did some searching through the archives and the best I could come up with was a 218 or maybe a 228?

Here isa link, but I would venture to guess this engine number is an 228, if it has not been overbored, or another crank, and rods were used say froma 251.

Here is the link http://t137.com/registry/help/otherengines/otherengines.php

You can contact B-Watson by PM, he will be able to detail the engine number for you. It is most likely a 228CI, about 110 hp.

Chrysler did not start using the 251in Ddoge and Plyms till late in the 50s, just before the slant 6 was introduced, they also had more compression, and hp, like to the tune of 125 hp.........

how long is the head??

how long is the head??

Greg, this a Canadian engine, all Canadian engines are 25 inch blocks, there were never any 23s made here. The C indicates a Canuck manufactured engine from Windsor Ontario plant....

Thanks for the link Rockwood, that was where I found the info about it being a 1954 dodge motor. But I couldn't find any info on that site that told me what Cu. in it was.

The motor was not bored over, they honed it out and then freshened it up from there. SO I am probably sporting the stock numbers....110HP doesn't sound too bad.

Hope to bump it up a little with the dual carb intake and split cast headers, a shaved head etc.

So anyone know for sure what Cu. in it is? Should I measure the stroke?

The 228 ci engine wil have a bore of 3 3/8 stroke 4.25, the 218 Engine will have a bore of 3 3/8 stroke 4.00.

I would lay money that for a 1954 engine it will be a 228, I do not think the 218 was made past the 52 or 53 year, but I could be wrong, it will not be a 251.......Fred

Thank for the info Fred.

I read somewhere on the board, while scouring the archives, that there is a plug on the head I can remove and put a long thin wire or stick in and I can measure my stoke that way?

[thrashingcows]

Should be over the # 6 piston.

OK will go out and see if I can locate it and pop it loose. Will I need to use a thread sealer when I re-install it?

[thrashingcows]

I pulled all the plugs and lubed the cylinders with oil, since it's been sitting a year or two since it last run. I then pulled the plug from above the number 6 cylinder and there seems to be some sort of internal plug?

Guess I can't check my stroke?

It is likely carbon, the wire should brake through with a bit of effort. How far did it go in? Put a chisle end on the wire and chuck it up in a hand drill and give it a spin or two. As long as it's not sitting on the top of the piston it should work through the carbon.

Yes, it is a Canadian-built 25" block engine. The Canadian plant built only 25" flathead sixes - no 23" blocks.

D49 2 5977 C

D49 - 1954 Dodge

2 - Regent

5977 - 4,977th D49-2 engine built

C - made in Canada

It is a 228.1-cid engine, with a 7.00:1 compression ratio and 108 bhp. The engine in that spec was first introduced in April, 1953, and was also used in 1955 on Plymouths and Dodges with the 3-speed manual transmission. The 1955 models with Powerflite used the 250.6-cid engine with an "X" at the end of the engine number.

Canadian-built 1942-50 Dodge Custom and 1951-52 Dodge Coronet models also used the 228 engine, but with a lower CR and bhp.

I was going to mention watching out for an engine hooked up to Hy-Drive, but as this engine was used in a P15 Plymouth I doubt it was. The Hy-Drive torque converter used the engine oil and pressure and thus had supply and return lines drilled into the back of the block where the bellhousing attached.

Sure doesn't look like carbon to me...it seems too neat with nice edges that don't fill up the threads. It really looks like a plug of some sort.

Thanks for the information Bill, I was hoping you'd chime in, since I've read a lot of your postings and you seem to have quite the wealth of information.

As you deduced this motor already has the 3 speed manual behind it so no worries about the Hy-drive.

228 CID. All Canadian Dodges of 1954 had that displacement.
