No Bux Rod Posted October 8, 2008 Report Posted October 8, 2008 In my quest for higher compression for my long block motor, I am trying to identify some Canadian Dodge and Plymouth cylinder head casting (part) numbers. Does anyone have a parts manual for Canadian Mopars form the late '40s to mid '50s? Alternatively, does anyone have a list of Canadian block prefixes? For example, what is the Canadian equivalent for a '53 Dodge D46? Thanks, N B R ------------------------------------------------------------ Wanted: '51-'52 Plymouth Business coupe (P22 Concord) Quote
PatS.... Posted October 8, 2008 Report Posted October 8, 2008 I have a 49 parts manual, but it just has Mopar part numbers, no mention of casting numbers. Quote

RobertKB Posted October 8, 2008 Report Posted October 8, 2008 My '53 Plymouth has the P24 engine and my '38 Chrysler is a C18. These are the same as south of the border. I have a spare engine for my '48 Canadian Dodge D25C that has D25 on it which is exclusive to Canada. My present engine in the D25 starts with a T and is a truck engine and a 251 CID. I would say that our engine prefixes are the same as the US ones except for where the car is uniquely Canadian like the D25. Quote
No Bux Rod Posted October 9, 2008 Author Report Posted October 9, 2008 Thanks guys with the help of Allpar I discovered what you have said. The only exception are the Canadian DeSotos that are really USA Plymouths. So a '53 Canadian DeSoto has the prefix of SP24 while the US version has a P24 prefix. All others are the same even though a '54 Dodge is a Dxx on both sides of the border. The motors are different....USA = D51 Meadowbrook or D52 Coronet 230" (short block) while Canada = D49 Kingsway; 228 (long block). Maybe this explains why the engine prefixes skip a digit or two ocasionally. N B R Quote

Maybe this explains why the engine prefixes skip a digit or two ocasionally. N B R Canadian DeSotos were virtually identical to American DeSotos. The "SP" DeSotos were export DeSotos built in both Canada and the U.S. and were never sold in Canada. They, and the export Dodge Kingsway models, were sold in Hawaii before it became a state. I do not know which Allpar article has that information, although I would like to know, as it is wrong! As for a Canadian version of a Dodge D46, there was none. The D46 was a 6-cylinder U.S. 1953 Dodge with a 230.6-cid engine. The only U.S.-style 1953 Dodge built in Canada was the D44 Coronet V8 4-door sedan. All other Canadian Dodge models were based on the Plymouth, with a 218.0-cid flathead six before April, 1953, and a 228.1-cid engine from April to the end of production. The D49 Kingsway was an export 1954 Dodge model that used a 228.1-cid engine if built in Canada and the 217.6-cid (early) or 230.6-cid (late) engine if built in Detroit. But the 1954 Kingsway was not sold in Canada. Canadian D49 models were Crusader, Regent and Mayfair. Quote

In my 47 Chrysler I have a D40 218.6, instead of the C38 251. Is this smaller engine incapable of RPM or sustained use as the 251 was able to do. I have a 3 spd standard trans regular clutch, and a 3.73 rear diff, with this current set-up. I also have a C38 engine, which is will need to be rebuilt, but eventually be used in this car, if all is well, don't think I will ever go back with fluid drive though. I have heard from oldtimers that the smaller 6s used in Plymouth and Dodge, were not able to sustain highway speeds as the 251 Chrysler enegine could, these guys said the 218 would get worn real quick at sustained speeds over 55 mph, where in the 251 Chryslers you could cruise all day at 65 mph. I would imagine that was more a matter of rear gears, as the smaller Dodges and Plymouths no doubt had stout 4.11 diffs, while C38 Chryslers had 3.54 and 3.90 diffs. On fluid drives, do you happen to know if the 1948 Chrysler Royal C38 Club Coupes came with the Fluid drive and 3 spd trans or fluid drive and M5 trans. My car started out as a 48 C38 Royal Club Coupe......thanx Fred Sorry Lowbux, not intending to hi-jack your thread Quote
No Bux Rod Posted October 9, 2008 Author Report Posted October 9, 2008 Bill, Here is the link to the article on Allpar site. http://www.allpar.com/world/vinlist.html Thanks for the detail you posted. The bottom line is that when looking at a canadian built Flathead Mopar 6, we should look for the "C" suffix on the engine number. Step 2 is to look up the 3 digit prefix (D49 for example) on your list above. Thanks, N B R Quote
