I think I may have figured it out. The vin on the block is xxxx121210803. That would be 6th digit designates year 1972, 7th digit designates Canada, McKinnon Industries. Looks like it's an L65, (165 hp that had a 2bbl carb and turbo 400 trans).
The K03 24. K= McKinnon, 03=March and 24 = day. Probably came out of a Chevelle still trying to figure that out. MelWff, thank you for pointing me in the right direction!
