239 crankshaft in 221 block

[Al ONT]

Well folks I have been reading posts and learning from you about flathead V8 Fords here since buying our 47 pickup last spring. The Oil pressure was low so I decided as a winter project to tear the motor down and repair as needed. Truck and motor is pretty much original with 24 bolt heads and I was expecting to find a 3 3/16" bore motor. To my surprise it is a 3 1/16" bore and has a small con rod journal crank with bearing shells inserts locked into the rods. And lastly the thrust shoulder on the rear of the crank has worn almost completely away letting the shaft move forward till the front crank throw was rubbing against the block at the main bearing. This is a Canadian truck and motor. In my research I have discovered that Ford Canada used this motor from 45 to 46 that has the crank throws drilled with two holes as to lube each conn rod bearing per the Canadian 41 to 47 Ford chassis parts catalogue.
So I tell you that story to explain why I'm asking if anyone has had any experience with installing the more popular 239 crank and connecting rods in a 221 block. It's not looking like I'm going to have much luck at finding a crank and new bearings for this unique motor.
