Ken_B Posted March 3, 2016 Report Posted March 3, 2016 I just stumbled across this forum doing some research about my new to me 1951 Plymouth Cranbrook. About me, I used to work in autobody/restorations, now I'm a Shipfitter. My long time dream car that I finally found is a 1951 Plymouth Cranbrook sedan, the same kind of car as my Grandfather's first car but with 2 extra doors. He had a couple 4 doors that I rode around in as a kid with him, they really made a big impression on me. My plans for the car for now are to clean the car up, it's about a 20 year old resto that's seen some daily driver duty. Do the necessary repairs it needs to keep it reliable. And then start to personalize it, a little bit of paint work, etc... The previous owner was unsure of the engine size, or any history of the car for that matter. He thought it might be a Canadian car, but I'm not completely sure, I'm gonna need some help from you guys on that one figuring out what to look for to say weather or not it actually is. If it is in fact a Canadian it should have a 218 ci Flathead 6 rather than the US market 217 ci, correct? The head does measure out at 25" so I'm leaning towards 218 ci, but wasn't there a couple different displacement sizes of 23" and 25" Flatheads? And couldn't somebody have just dropped a different engine in the car at some point? anyway thanks for the help! I'm glad to have stumbled across this site!The two pictures are; My Cranbrook the day I got it next to my old Valiant I traded for it. And a picture of my Grandfather with his Cranbrook around 1961 or so. 1 Quote
casper50 Posted March 3, 2016 Report Posted March 3, 2016 welcome Ken. Someone will be along shortly to answer your question. I think a dodge with an original 25" block would have been made in Canada. Quote
dpollo Posted March 3, 2016 Report Posted March 3, 2016 If it is a Canadian car, the serial number will begin with a 9. This number is found on the left front door pillar just above the hinge. There will be an aluminum tag on the firewall with the body number paint and trim codes. Also it will have the 25 inch 218. It will also use Spicer cross and roller U-jointe same as Chev later used in the 55-6-7 models and there are a number of other differences. The picture you posted shows a pretty nice car. They are really nice cars to drive, I have had several, the present one being a convertible. 1 Quote

I guess my next things I need to figure out are how to be sure it is a 218 ci and not a larger displacement variant of the 25"(previous owner claimed it had been re-ringed and had new bearings in the last few years, said it was a nightmare getting the correct piston rings for it.). And what parts numbers and availability of the Spicer u joints as they are on my to do list. Thanks, I am very happy with it! I would have to agree they are very nice driving cars! Quote
deathbound Posted March 4, 2016 Report Posted March 4, 2016 I believe the engine# should be stamped on the outside of the drivers side frame rail.....somewhere around the rear axle, maybe just behind. It may take some CSI to find it & the locations vary slightly, but if the #'s match, it's the original engine. Welcome & nice looking car. Dig the picture of your Grandfather, looks like it was a mild kustom. Quote
dpollo Posted March 4, 2016 Report Posted March 4, 2016 (edited) Rings would have been easy to get if American parts books recognized the engine. Hastings # 804 If it is the original block it will carry the engine # beginning P23 ............. . this number will be also stamped exactly 13 inches behind the rear axle on the left frame rail. The original bore size was 3 3/8, stroke 4 1/16 . Nowadays a popular rebore for this engine is + .o6o which is 3 7/16, the standard Chrysler 251 bore size. Your engine uses the same gaskets, bearings and seals as the Chrysler and Desoto. as for the universals, they are the same as a 55 Chev........Numbers , depending on the brand , Neapco 1-0153 comes to mind. Easy to get provided you do not ask for joints for a 51 Plymouth. Better check underneath since they went back to using Detroit joints for '52. The cross type were 46 to 51. I highly recommend the Plymouth Owners Club and also Neil Riddle in Seattle area is a good source for parts. Bremerton is not very far from where I live and lots of Canucks worked in the shipyards there so maybe that is how your car got down there. Good swap meet in Bremerton, too.

rb1949 Posted March 4, 2016 Report Posted March 4, 2016 (edited) Nice ride. I noticed the classic, with the narrow WW tires. Are they Radial, on stock rims? Edited March 4, 2016 by rb1949 Quote
JerseyHarold Posted March 4, 2016 Report Posted March 4, 2016 Welcome to the forum. Beautiful Cranbrook. P23's are my favorite cars. Having a Canadian car will keep you on your toes when it comes to finding parts due to the differences from US cars, as I'm sure you've discovered by now. Quote
dpollo Posted March 5, 2016 Report Posted March 5, 2016 Here are somethings you may not know. Canadian cars use a different frame so the steering box mounts further forward to clear the longer engine. The steering column and shaft are longer. The front springs are heavier and the king pins have roller bearings at the top. The radiator is different with the upper hose entering on an angle. Horns are different since there is less room in the space behind the grille. The brake drums have a different profile making it impossible to mount the wire wheel optional for 52 and later on the rear. These drums will interchange with US models. The air filter is wider and lower and there is no filter in the road draft tube. Canadian Cranbrooks in 51 and 52 use the rocker moulding and gravel shields used on the 50s. The original colours were subtly different from US models and the inner surface of the trunk was painted body colour in Canada. Generally speaking, cars sold in the USA had higher levels of trim and options although everything was available, just more expensive in Canada. My Cranbrook Convertible sold new in Victoria BC for $3485 with no heater or turn signals. That is almost $1000 more than a similar car delivered in the USA . FOB Detroit was $2222. I do not know what FOB Windsor was. Quote
Ken_B Posted March 5, 2016 Author Report Posted March 5, 2016 rb1949 Yes the tire are radials mounted on stock wheels with tubes inside. That is the one thing the previous owner did have some knowledge about the car. He told me had them mounted at a Les Schwab and they removed the small metal tab from inside the tire and patched it allowing tubes to be used safely. Thank you for all the great information dpollo!! This will definitely be very helpful in the future! I had no idea there were so many differences between the US market and Canadian market cars. I will definitely be checking out The Plymouth Owners Club. How would I go about contacting Neil Riddle if I needed something, is he a member here? If anyone would like to see more of the car, I plan on giving it a good wash and wax this weekend if the weather lets me. I will try to get some more pictures up here to show it off. Quote

1950 Special Deluxe Posted March 5, 2016 Report Posted March 5, 2016 My car is also Canadian. It is a Dodge Special Deluxe, very similar to the US Plymouth version but with the 25" block. I have an original manual and parts catalogue. They are very handy in locating parts. Quote
dpollo Posted March 5, 2016 Report Posted March 5, 2016 (edited) By all means let's see some more pictures. Edited March 5, 2016 by dpollo Quote
dpollo Posted March 5, 2016 Report Posted March 5, 2016 (edited) Neil Riddle advertises in the Plymouth Bulletin I don't know if he is on this site but there are other Washington residents with 51-2 Plymouths on here. I have added another difference to the above list. All these variations did not make the cars better, just different but it was nice as teenagers to be able to drop a Chrysler 251 right in without any modifications. I rode in one with a 265 Chrysler six and was very impressed. I later built one and put it in a 50 for a friend. He tore up 2 clutches and a transmission but we are still friends. The nicest running of all the flathead sixes, in my opinion is the 3 3/8 bore x 4 1/16 stroke 218 when it is bored .060 ( 3 7/16 ) They run really smooth and can be revved up higher than the longer stroke models.

Ken_B Posted March 5, 2016 Author Report Posted March 5, 2016 Thanks for the info on Neil Riddle and finding some parts! The number stamped on the side of the block does start with P23, so it looks like we have a 218. I will have to clean off the drivers rear frame rail and see if the number is a match. I found a box of gaskets and rings going through a box of spares that was included in the trunk. I'm going to have to do some digging and see what I can find with those old parts numbers. At this point I am hoping it has been bored to 251, that's a pretty good jump in displacement. Looks like the weather is going to cooperate today for me to clean it up and get some pictures too! Quote
dpollo Posted March 5, 2016 Report Posted March 5, 2016 Boring a 218 +.060 does not make it a 251 far from it. Sorry if that was what I implied. You are only using 251 pistons when you bore .060 and beyond. The stroke of a 218 is 4 1/16. a 251 is 4 1/2 , so the increase in displacement is largely due to the longer stroke. In my 51 Plymouth I have bored it to just under 3 1/2 which is 3 7/16 + .060 and it uses the 251 crank and rods so the displacement is now 260 cubic inches. With 8.5 to 1 compression it is a very good performer and at 50 000 miles of use, it still runs like a champ ! Should I ever replace this engine I will go to 3 7/16 but use the original 218 crank and rods because I like the way these engines can be "wound up ". Chances are though, I will not ever need to change it out. It also has Overdrive, a VERY pleasing option for highway travel. One should never believe what someone says about his sex life or his gas mileage, but I can get over 25 mpg on a highway run. As for the other, no comment. 1 Quote
Ken_B Posted March 6, 2016 Author Report Posted March 6, 2016 The weather was great today, I was able to get the car out and all washed and waxed up. She cleans up well! I definitely still need to do a good cleaning on the interior but every time I look at this car I am more and more happy with it! Anyways as promised here are some pictures. 1 Quote
Niel Hoback Posted March 6, 2016 Report Posted March 6, 2016 "Oh, the fun you're going to have." Dr.Seuss. That's a fine looking car you've got there. Take care of it and it will take care of you. Quote
dpollo Posted March 6, 2016 Report Posted March 6, 2016 If I am not mistaken, the colour is called Opal Gray # 4154 on the body tag if the car is early production or 4204 if later. Dulux code DU 4 It is an easy colour to match having a mix of about 2/3 white, 1/3 black and a little orange. Thanks for posting the pictures. That is something I have not yet learned to do. Quote
_shel_ny Posted March 6, 2016 Report Posted March 6, 2016 (edited) There is more than one way, but the easiest way that I find to post pictures that are in my computer is to scroll down a bit. On the right you will see "more reply options". Clicking that will open a window where on the left you will find "Attach Files" That will let you browse, and attach your stored pictures. I usually resize mine before loading to save my allotted site space. I try for less than 150kb If a pic I want to keep, I copy then resize before posting. Also, if the pics are too large they overfill the screen making it difficult to view. Edit: I also try to reduce the size of the pics to allow for attaching more in one post. As well as having a limit on the total kb per individual on the site, there is a limit size per posting. If you exceed your site limit you will have to go into "manage attachments" and delete some before adding more. Edited March 6, 2016 by shel_ny 2 Quote
dpollo Posted March 7, 2016 Report Posted March 7, 2016 Thank you, I did try to post a picture of my 51 convert but will have to go to manage attachments and reduce the kbs. I have never accepted overhead valves let alone electronic marvels. I use the excuse that I was born in the first half of the last century, Pretty lame, but it works for me. Quote
Ken_B Posted March 12, 2016 Author Report Posted March 12, 2016 Ill have to do some looking into that color info, I know the car was repainted at some point, but I plan on redoing it better. I sure do love driving this thing! Quote

rb1949 Posted March 13, 2016 Report Posted March 13, 2016 They allow 195MB of photo 'storage' per user. At 500x600 size, that's about 2,000 photos to 'attach'. Every computer has the program PAINT. In 2 clicks I resize original images down to 35% of original size for here. (Save it with a different name) Do the same before uploading to on-line storage. I found "Picture Trail" to be quite easy. If using the 'link' to insert a photo from a site, it can be bigger, and you're not using forum storage, so add as many as you like. (After uploading, I immediately copy the needed link to the image, then save it in a notepad file for future use.) Quote
dpollo Posted March 13, 2016 Report Posted March 13, 2016 Many thanks for the advice. So far I managed only to get a thumbnail onto the site, but deleted it. Quote
