Shortening up a bw78 to go under a Val.  Current has a 2.92:1 type 75. I've run a 12.5@107. The 3.45:1 AU rear axle should knock a tenth or two off that 

He'l yeah.....hiw.much shorter is the valitank housing

It ain't slow. It's even better that it was done with such a steep rear axle too.  I know another user on this forum who's run quicker on the same ratio.  But they had a tacho, and a proper shifter. 

So what are you hoping for 12 flat or high 11s

*I think you can have a 74/75 carrier machined to take the 4 spider bits out of a 78*

I don't know to be honest.

But from fucking about with diff swaps I'd say,

Can you get a Quaife LSD for the Cortina/Atlas diff?

Is the width close to a Hilux?

What are the chances of finding a 9" that someone has shortened for a Cortina back in the day?

In my experience the cheapest option often ends up more expensive.

Very true Pete..

The easiest option mate would be 25 spline xa.b.c.d.e.f 25 spline lsd diff and put the lad in the Aussie cortina housing..

And I'm still on the hunt for 1
