For reference, my stock case Glide with a JW BB Bell and deep pan is 123lbs.
The PowerGlide weight will depend on a lot of parts you pick (and pay for).
The cast iron valve body is very heavy, and transbrake valve bodies are available both cast iron and aluminum.
Steel or cast iron drum vs aluminum drum.
JW bell, and my stock style crossmember mount has some weight too.
My PG trans weighs 129 lbs with J.W. Ultrabell for big block Mopar. Includes cast iron transbrake, deep pan, 7 clutch ATI steel drum.
You can get a PG down to about 100 lbs with aluminum valve body and aluminum drum, etc.
