Gotta disagree with you there, Frank. According to Marcel Chichak 
(http://www.telusplanet.net/%7Echichm/tech/lucastuning.pdf), the weights are 
the same throughout a distributor family. The only differences are the 
springs and the length of the arm on the cam. The arm limits total advance 
and the springs control the actual rpm curve over which that advance occurs.
