The Canadian C69A series engine was set up with shells on the rods. They have unique bearings that are thicker the 8BA types and I've heard that they are getting harder to source. A person can change the crank and rods over to 8BA types so at least the bearings are abundant. The C69 usually has the number on the back bell housing part of the block. These were post war engines that came on line somewhere in 1946. Inspect the oil porting on the back of the engine carefully. Some Canadian engines still had a pressure flow oil filtering system that was carried over from WWII. It has to be connected properly prior to use or the engine may not have oil pressure. Some applications even used an oil cooler set up.
