dontknowitall Posted January 12, 2010 Report Share Posted January 12, 2010 Hi folk Can anyone tell me if my T173 engine is called a "251". I am going to order parts from the states and the good folk keep on refering to parts for a "251"... it just makes me a little insecure. see below vehicle 251 engine Vintage Power Wagons, Inc 302 South 7th Street Fairfield, IA 52556 Qty Item Description price each Amount 1 Eng.

norrism1 Posted January 12, 2010 Report Share Posted January 12, 2010 (edited) This what is shown on the DPETCA site T173 218ci Dodge Truck Canada DE-1, DF-1, Fargo FM-1, FN-1 1949-1950 Better verify with them before ordering and payment. But if the engine number starts with T173, Like I said. Edited January 12, 2010 by norrism1 Quote Link to comment Share on other sites More sharing options...

Tony WestOZ Posted January 12, 2010 Report Share Posted January 12, 2010 (edited) T173 is a 218 Canadian long block. I believe 251 pistons at 40 thou over will not fit. It leaves the cylinder wall to thin. You would need to get the walls ultru-sonicly tested to check first. Standard size 251`s approx = 218 + 60 thou. these should work. The bearings and valves and oil pump are the same on the 218 and 251 Just had a thought, I think the piston pin heights are the same for a 250, 218 but it might pay to check as they run differant cranks and rods.

dontknowitall Posted January 13, 2010 Author Report Share Posted January 13, 2010 thanks tony, i will pass it on to my supplier.. Quote Link to comment Share on other sites More sharing options...
dontknowitall Posted January 14, 2010 Author Report Share Posted January 14, 2010 well Tony you saved the day! after posting your reply, i went myself to the mechanic and measured the block. The measurement given were way out! It shows you to check and double check always! i would have ende up with a whole lot of wrong parts. The correct measurment the block face = excactly 25. 5/8" inch, this is measured from end to end on the face (not the head, just the face) The Piston / Bore = 3. 3/8" inch Conrod lenght = 8" inch measured from centre of the pin (top of piston) to centre of where the bearing is held. so, this time ...

Tony WestOZ Posted January 14, 2010 Report Share Posted January 14, 2010 well Tony you saved the day!Not yet after posting your reply, i went myself to the mechanic and measured the block. The measurement given were way out! It shows you to check and double check always! i would have ende up with a whole lot of wrong parts. The correct measurment the block face = excactly 25. 5/8" inch, this is measured from end to end on the face (not the head, just the face) The Piston / Bore = 3. 3/8" inch Conrod lenght = 8" inch measured from centre of the pin (top of piston) to centre of where the bearing is held. so, this time ... I have never had a 218.06 apart. I would have thought the rod would be a bit longer to allow for the 4 1/16" crank. The couple of mesurement I would like to know if possible, is the distance between the centre of the piston pin and the top of the piston, and the how far the top of the piston is down the bore. With these I can check the deck height. 218.06 long block pistons might be hard to get. I don`t know that the used these in the US were they had the short block 218 (well 217.something){brain fade} Hav`nt you got a KEW sitting there? Mmm, Now if the crank and rods out of the 250 Kew went into the 218 block........ I`ll have to think about this. Quote Link to comment Share on other sites More sharing options...
dontknowitall Posted January 14, 2010 Author Report Share Posted January 14, 2010 hey Tony, all to tech for me.. I am not a mechanic. you must have been or still are a mechanic? The Kew I am trying to get going and hope to sell it to offset some of the cost of rebuilding this engine. see the email reply from vintage power wagons after the adjustment. Ryan, that is close enough. Depending on the stroke of the engine it is probably a 237cubic inch or a 251 cubic inch motor. The stroke on the 237 is 4-1/4" and the stroke on the 251 is 4-1/2". If your rod is 8" long center to center it would be a 237cubic inch motor. When these engines were prepared at the factory they gave them an engineering code that they stamped below the engine head on the drivers side of the block. This number indicated what plant the engine would be shipped to and what it would be put in. We sell the Chrysler Engine manual for these old engines would recommend adding it to your order as it makes very clear what this engine is and all of the specifications and tolerances that Chrysler specified for rebuilding them. We will adjust your invoice and make sure that your receive the engine parts for the 237cubic inch engine. When ordering engine parts in the future you will now know that you need to order for a 237 cubic inch. Glad we figured this out and we can add that $28 engine manual to the invoice to help your mechanic and you through this process. Hope this helps, Steve I am glad when this is done.. then I can do what I know best..Panelwork ! I have never had a 218.06 apart.

Tony WestOZ Posted January 15, 2010 Report Share Posted January 15, 2010 The Piston / Bore = 3. 3/8" inch I think the guy at Vintage Power Wagon should read the book he is trying to sell you. 3 3/8" bore engines of this time were either 218.06 or 228.12. Not the 3 7/16" of the 236.6, 250.6 and 265. T179 is the engine code for a 236.7 Quote Link to comment Share on other sites More sharing options...

Tony WestOZ Posted January 15, 2010 Report Share Posted January 15, 2010 (edited) Tony, Its a 173.. Sorry, yes I know yours is a T173. It was a go at Vitage PW. I would have assumed they knew the difference. Edited January 15, 2010 by Tony WestOZ Quote Link to comment Share on other sites More sharing options...
