T5 conversion ?

[unklesam]

hey, just looking at powerplant options for my son's FB, it was registered here with a red and 5 speed Toyota (which seem to be getting thin on the ground) reading elsewhere people were saying the Falcon T5 into Torana's but by the looks of them they are a big unit and would need more work then a Toyota to fit ?? has anyone experience with them ?
Otherwise seeing as I have time on my side will just keep my eyes open )
