Well this is what i was able to come with. Not sure if it'll help you out or not.
This could be the possible C6 engine, was'nt clear for sure though. You'd have to see if it looks similar to the one in your kit.
You could also try looking around on here http://www.killervette.com/photogallery/
they have a photo gallery of all sorts of C5r pics.
Hope that gives you a little help.
