John-
For the cam, I would contact Earl Edgerton of Edgy Cams. You can contact him through his website:
http://www.visionquestwebdesign.com/edgycams/ Earl did Don Coatney's cam, and races a long block Chrysler flat six on the salt in a '33 Chrysler. He can probably answer your questions about the rods too.
Here's a pic of his race engine, a custom 12 port fuel injected flathead with lots of one off aluminmum castings...
