You can start here with your research :

then there are about 2-3 good Miura sites with additional details and about 8-10 Miura owners on LTalk when you start getting into the really detailed questions that generally only owners can answer.

Also, if you dig into the Old LTalk we had several long, indepth talks about Miuras. The site owner here owns an award winning Miura so I'm sure he could help also.
