The Ford Barn - View Single Post - German H-block?

Those two holes that B&S refers to in the pan rail is a feature of ALL Canadian blocks with shell main bearings. Is the easy way to identify 36 LB engines without tearing them down. [Look/feel behind the crank pulley for a 5/8 dia hole].... I think they were used in fixtures in the factory when they machined them.
But that block is NOT a canadian block
The crankshaft used in those early 81A engines was the same 2.4 dia mains job used from 36LB through to 38. Runs the fanged rod bearings. That appears to be what your block has. As you say, special thick wall bearings
