Aren't they the same physical dimensions as an LS2?
Readily made mounts available I think, need custom sump, I think rails and firewall lip need to be trimmed...

I thought all those LS engines were basically the same
Andy (LS2hatch) will probably know for sure
Don't quote the job... you're bound to lose money... since it aint going to be a drop in walk in the park

The LS3 is basically the same as the LS1, LS2, L98 etc.
There are off the shelf engine wiring harnesses, engine mounts and oil pans but you will need to make custom headers. You will also need to put together an EFI fuel system and run cats. The computer will require programming to disable the VATS. Gearbox choice will affect how much transmission tunnel modification is required. If you are not running power steering then you will need to replace the power steering pump with an idler pulley or change the belt configuration.The car will require engineering, better than factory brakes and a stronger diff.
My advice would be to only takeon the job if you have access to a Torana that is currently running a LS engine with the same transmission as the client intends to run. That way you can price up all the parts required for the conversion and the chances of parts not fitting will be reduced. I suspect once the client sees the cost of the parts required they will loose interest in the project.
You may also run into difficulties registering the LS3 depending on local rules and the tare used.
In WA under the NCOP the maximum displacement naturally aspirated engine in cc is five times the factory tare of the heaviest model in the range. In WA they like to use the tare 1204 kg which gives a maximum cc of 1204 x 5 = 6020 cc. The LS3 is 6162 cc.
The heaviest model in the LH/LX/UC Torana range is the A9X sedan which has a tare of 1306 kg. This gives a maximum displacement of 1306 x 5 = 6530 cc (398 ci). You may have to go thorugh some red tape to get the rego department to accept the A9X tare.
