to PackardInfo. Usually I invite new Forum Members, if they haven't already done so, to include their Packard/s in the Packard Vehicle Registry. But, seeing the only thing Packard in your car is the transmission there's really not enough there to qualify as a Packard automobile. 
Concerning, turning 5,000rpm at 60mph this is most likely to be a function of the ratio in your Chevy truck's rear end which is likely to have a stump puller ratio because it is from a truck. In top(3rd) gear, the Packard trans should be a 1:1 ratio, therefore not impacting the revs required to get your car down the road.
Little sideways shift, speaking of Packard trans in non-Packards, I had a Packard trans in my dragster back in the late 60's mated to a 289 Ford V8 and Ford Customline "Ute" rear end with 4.1:1 gears. Only ran 2nd and top in the trans, with a best ET of 10.37secs @ 137mph in the quarter.

To be honest, I'd really like to get more gears in it as it currently spins 5000rpm at 60mph.......I have a similar thread on a Chevrolet truck forum trying to identify the rear end. Near as I can tell, its from a 1947-1954 Chevrolet "Stovebolt" pickup truck.....
