Happy 46R Posted July 26, 2022 Report Share Posted July 26, 2022 This is probably more for the Canadian followers but today I picked up an engine to use as a spare if needed. This engine will need some grooming I am sure and would only be used as a back up if needed. It is a 25" block and according to the seller came from a 1947 Plymouth convertible that is currently being rodded! The interesting information for this engine is the serial # begins with a T112- which is totally different than my 46 Dodge which begins with the qualifier D and then the model # 25C. Does anyone have any literature on engine numbers for 40's Plymouths that indicate a letter prefix of T? Also of interest was a tin medallion that was riveted to the side of the block. It shows a rebuild in Winnipeg Manitoba with a .30 overbore on the cylinders but nothing to the mains or rods. Has anyone got any information on these tags or who to contact to chase the numbers on it. I am just curious about the history of my back up engine before exploring all of its parts and pieces.

Sniper Posted July 26, 2022 Report Share Posted July 26, 2022 T means truck https://www.t137.com/registry/help/otherengines/tengines.html T112 is T112 201ci or 218ci 23 inches Dodge Truck WC, Some WD 15 1941-1947 Quote Link to comment Share on other sites More sharing options...
Happy 46R Posted July 26, 2022 Author Report Share Posted July 26, 2022 (edited) Thanks Sniper quick response. I measured the block and it is 25" so more detective work required. I am guessing that would make it the 218 ci? Would you think the US numbering system and the Canadian system would be that different?

Sniper Posted July 26, 2022 Report Share Posted July 26, 2022 (edited) If you look at the link they do spell out Canadian version vice US, but I don't know that they get them all either. Now if it was a T122 vice a T112 then it would be a 25" engine out of a Dodge truck. Might double check that number Edited July 26, 2022 by Sniper correction 1 Quote Link to comment Share on other sites More sharing options...
RobertKB Posted July 27, 2022 Report Share Posted July 27, 2022 (edited) This from a Canadian parts book so 25” for sure. Definitely a former truck engine. Block was obviously bored. My guess is the crankshaft was terrible so a new one was used, hence the standard mains and rods. Remanufactured Chrysler Method tells you it was done by a rebuilder that was Chrysler approved. I had a similar tag on the engine in a ‘38 Chrysler I have since sold and for which I now have seller’s remorse. It was also a former truck engine but a T311 so originally a 228 CID.

Happy 46R Posted July 27, 2022 Author Report Share Posted July 27, 2022 Unfortunately my acquisition isn't quite as nice as yours but I will document it's dissection and rebuild carefully. Thank you everyone for your feedback. Dave 1 Quote Link to comment Share on other sites More sharing options...
keithb7 Posted July 27, 2022 Report Share Posted July 27, 2022 As a spare engine, you’ve got a lot to work with there. Plenty of good spare parts. Carb, manifolds, generator, distributor, starter and lots more. I’ve salvaged many a part from my spare engine. Spare parts really save you a lot of time and money. Just recently I needed a cylinder head. I had one. Imagine the potential freight costs on that hunk of metal. 1 Quote Link to comment Share on other sites More sharing options...

Good luck with your project! 1 Quote Link to comment Share on other sites More sharing options...
James_Douglas Posted July 28, 2022 Report Share Posted July 28, 2022 Costs for parts have become ridiculous. When I did the rebuild of the '47 about 20 years ago that engine got a NOS cam, NOS Head, and NOS crankshaft. The cam and the head were each about $100 delivered. The crankshaft from NJ to CA all in was $225. I hate to think what people would want for those today. James Quote Link to comment Share on other sites More sharing options...

keithb7 Posted July 28, 2022 Report Share Posted July 28, 2022 @Happy 46Rafter a decent, thorough engine rebuild up here in Canada, I ended up at about $5,300 Canadian. Doing all the labor myself except machining. All New pistons & rings new cam & all tappets new timing gears and chain All new valves new mains, rod and cam bearings piston pins & bushings, c-clips all new seals and gaskets Rebuilt generator bored cylinders over crank mains .010 under. Rods .001 polish valve grind & lap Head milled & new head bolts block & head hot tanked & crack checked Con-rods tested & re-used new oil pump speedi-sleeve front crank seal area Parts were ordered and in-hand by March 2020 I think it was. (the pandemic period is a bit blurred). I’m sure parts prices are up considerably since then. The above price included about $400 in extortion fees.
