But I have a /6 so a 500/518 won't bolt up.
And my kid has a 440 in a c body wagon, again a 518 won't bolt up that's why I'm thinking about gv.
There is/are companys that can provide an adapter bellhouse. Maybe they do slanty bells too, IDK.
JW Performance Ultra-Bell" is one.
Below is a bell for BB to 727. I also saw one for BB to TH350; so that should include the 700R4/ 4L60 series.
They appear to bolt on to the pump; so you can use your trans with the bell cut/machined off.
BTW
You probably know that the GVod can be had as a stand alone unit. You would have to build a mount for it, which probably means cutting up the floor a bit, but that would make it transferable, without adapters.

But, I was thinking, with a 440, on the street, is there really a need for an overdrive. I'm talking street duty.
I didn't buy my GV for it's reduced cruise rpm; I have never even installed the little controller it comes with.
No; I bought it to split gears with, so I could run a small-cammed, small engine, and have BB type Eighth-mile performance, yet the small cam would get me plenty of bottom-end BB-type torque, yet 318 type fuel economy.
If I actually had a BB, and needed the reduced hiway rpm, I would just gear the back for whatever rpm I wanted, and then to get the First-gear performance back, I would just increase the stall.
By the time you get a new GV installed, what are you looking at? $4000? or more?
What's a good used 3.23 chunk worth? (I mean people almost give these away, and I bet you already have one), and a new 2800/3000stall TC? I mean both together will be a fraction of the installed cost of a new GVod.
Even an Ultra-Bell plus a usable A518, no hi-stall, and no rear gear change; will probably come in at a similar price to the hi-way gear/ hi-stall combo.

Maybe there is even a company that makes a flat-plate adapter to bolt an A518 directly to the BB; IDK. Many many years ago I think there was.

Ima thinking you have already explored all these ideas so Ima probably just blowing smoke ....................
