According to a post from "Rusty O'Toole" in this forum on 22 June 2007,
"The small Plymouth/Dodge block is 23 1/4", the big DeSoto/Chrysler block is 25 1/4".
"For your block there were many possible combinations from 201 cu in (Canadian prewar Plymouth) to 265 cu in (52-53-54 Chrysler Windsor).
"Crankshaft stroke length available for your block are 4 1/16", 4 1/4, 4 1/2 and 4 3/4.
"Common bore sizes are 3 3/8 and 3 7/16.
"The same pistons will work with any crankshaft but you must have the connecting rods of the correct length to go with the crankshaft. In other words if you use a different crank you must use the matching rods."
Don Coatney, who is active on this forum, has shown us many pictures of his 251 cid DeSoto "long block" in his 1947 Plymouth. It looks mighty fine in there.
God's Peace to you.
