Help Required: Slant 6 Engine Identification

I'd question the 5-plug blocks commencing with VF's

Your argument is with Chrysler Australia's parts catalogue :-)

Thanks also for decoding the engine number, but from that information are you able to identify what horsepower my engine is?

145 -- the only rating available in the US/Canada at that time.

Lucky I'm a Fitter/Machinist I can do this easily, but I don't suppose anybody has a dimensioned drawing of what is actually needed so I can pre-make the required part?

Oof. Somewhere I've got the nominal dimensions of the small torque converter nose and the large crank bore, but those won't be precise enough.
