Licenced to kill, The earlier post by Graeme is correct; you are Canadian, as is your engine. Those really thick, lock in shells you describe as out of your engine are a Canadian only thing. As New Zealand Fords were sourced from Canada, these things are quite commonly found down under, however, the majority of posters on this thread, being from USA, haven't seen this stuff. Your crankpins will have double holes in them in order each bearing gets lubed; the American full floater cranks only had one hole per journal, which lubed the entire full floater. Your conrods have those notches from the factory, the American rods, on account of the full floater design, did not have any need for the notches.
Now, the good news is that you can use your crank and rods with either the original style lock in shells, or the regular USA full floaters. All journal sizes/ rod bores are the same. You cannot use your lock in shells and rods on a single hole journalled crank!
