Ah! So it might have the early model 5.7 litre motor then. Just another question, were the early Diablo motors EFI conversions of the Countach motors? Because power outputs seem eerily the same. Also, logically a small company would be interested in "recycling" as much of their expensive parts like the engine as possible.
As for the eye, well, if your photos have engines in them, I'll be looking extra hard!
Thanks for your detailed shots BTW! It's eye-candy for me. 
EDIT: Google is your best friend. This is a Diablo engine. The shape of the plenum chambers dictate that. The Countach engine did come with EFI in the US from 85 onwards and was 5.2 litres, not 5.7 as in the Diablo. Still, it could be a modification of the engine. Sami needs to get a life and get out more - tsk tsk tsk
