I just looked at some specs and was curious why this one instead of the later heavier version or wouldn't that one fit. I wonder about the lower torque rating.

Why the GM 4L460E rather than a 700R4 or 200R4 or some other trans????
I have not seen Kevin's installation, but from his explanation to me over the phone, the 4L60-E (or 4L60) has a removable front "bell housing" unit. This allows it to be mounted in many different cars simply by changing the converter cover/bellhousing. Here's a picture of a typical one:
As I understand it, the way the conversion was done was to cast a machinable replacement converter housing/bellhousing which can be bolted to the 4L60 and the Packard engine block.
On the other hand, the 4L80-E housing is one piece which would require machining the housing itself ala the 700R-4 and TH-400 conversions:
