It's a bit tight in there to get a good clean picture of what you're asking about, but here's a look from the top.
It's hard to see, but here's a shot close up (my phone couldn't get any further away and still be able to see it). It's actually above the bottom of the crank pulley by an inch or two. It appears to be no more than two inches though.
This one kind of shows how much higher it is, granted, there's no belt in it yet, so the tensioner sits lower...
I can try a different angle if it helps, but I'm not sure if it will be much better than this. Let me know if you want something else and I'll try and get a photo.
