| VIII I send you the Morse Chain lay outs under separate cover. Also a preliminary Cudillac instruction book which please do not loose. They have not even yet made any 12's and 16's this year due to new tools & strikes. I send you four M.E.P. Curves of the whole Cudillac luSalle run together with their timing, these will be of great value to me for reference, the minimum negative overlap of 11° is interesting. The two axle ratios available on the C6 are 4.64 = 88 M.P.H. at 4500 & 4.31 95 M.P.H at 4500 I shall go for the lower ratio RM{William Robotham - Chief Engineer} | ||
