Warbird Information Exchange

I recently purchased an OX-5 for a 29 Curtiss Robin project. I have had several people talk about the Miller conversion kits for the OX-5. I have tried to find information about the kits on the net, but it is limited or I just can't find it. Could someone explain what the Miller Kits included, what they did for the OX-5 and steer me to a book or website where I can learn more. Also, if someone had some good pictures that would be great.

Thanks
