mate ill keep this short.the money itll cost you to buy a barra 270kw engine you would be better to turbo a 250 and with the rest of the money you save do the rest of the mods to your car.as for the nine inch yes its got to be shortened.
i agree the money would be better spent on turbo'ing a 250 x-flow or even better a 4L OHC motor, pref a low k AU (stronger bottom end, metal head gasket.etc)
"Do you think the 250 would make a decent amount of torque?"
that is an understatement!! a turbo 250/ 4L OHC would make bulkloads of torque, more than a barra if tuned and built right.
it would be better starting off with a factory 6cyl, as i think the tranny tunnel may be bigger,slightly diff front susp., i think the steering linkages may have been different to clear the motor, the brakes(although i would assume u would put bigger ones on....) and there were a few other things i cant remember
the diff. is also different i would stick with it. just find a 4-pinion LSD and get a specialist to "tighten" it up. my brother has an 302 xa coupe 250hp at the wheels several burnout comps and 7500 revs, and its still goin strong. but it if u are goin a manual the nine inch may be a better option.
i doubt the hubs from an au would bolt on to a corty, but u never know.
Myself i'd use a Toyota 2JZ twin turbo six. And keep the B/W diff as said above. Hopper Stoppers do the brake kit now for the TC-TD. And use a 6 cylinder Cortina as they have the fire wall cut out to suit the six.

the 2JZ GTE motors are awesome and one of the stongest motors made! it would be the best option power wise and reliability wise.
depends how much a conversion will cost(excluding motor/ecu), maybe in excess of $2500/3000, dunno what tranny youd use. but it "could" cost a lot less than turboing a ford motor to get the same power.
the only thing is you need to do a lot of research either way, to get the result u desire.
measure up a 2JZ or 1JZ. check clearance issues such as exhaust, intake,accessories. etc.
a BA motor will aways have more potential than any other aussie ford six.
AU would be a cheaper option and a better one in my opinion as it would cause less hassles and be plenty reliable with th right tuning and setup.
the BA or toyota 1JZ /2JZ would be awesome conversions but may require more research and thinkin.
ask some questions and tell your concerns and approx budget and me and others will be able to provide better info
an au engine does have a stronger bottom end cos it has a cast alloy sump which forms parts of the bottom end. it's a pity u cant use it though cos the hump is at the wrong end. if u'r gonna go to that much trouble to make up a sump do it to the barra engine. it'll cost u more than a turbo 250 but it'll be something different and very special.
