4l80e = .75 od ratio
GV = .78 od ratio
The 'plus' (if there is one) is the GV unit offers the ability to use it as an under-drive in all gears so you get the HD aspect of a th400 w/the possibility of a deeper 1st/2nd like a 700r4 w/o the big ratio split they suffer from.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
