| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to CJ. HS.{Lord Ernest Hives - Chair} S E C R E T. X9060 E1/M6. 6. 24. E+ A.{Mr Adams} C. VALVE LIFT CURVES WITH LOWER LIFT. X.9090 X.9060 We send you herewith drawings Nos.Lec.1880. 1881 and 1882 dealing with the above. The first named deals with the geometry of the rocker, and shews that a cam lift of .325 will give us a valve lift of .423. These are the dimensions we wish to work to using the existing valves, rockers, and springs. Would you kindly instruct the necessary formers to be prepared for these cam curves.
