LE0 is an Alloytec V6.
Check out this list. It's huge, but go to around pages 80-90, where you'll see all the engine codes starting with L...

I suspect it's not really the answer you are looking for though. You would be better off googling the different Holden models, which will tell you what engine codes were fitted, or, you might be better off doing searches on engines that other people have used in their conversions, before you create a massive headache for yourself.
