We attach herewith blueprint of LeC.3222 shewing a Turbulent Type of Cylinder Head with a Lipped opening for the above chassis. Will the Experimental Dept. please have the small alteration to the pattern made to the dimensions shewn on the LeC. and castings made. E.Dept. should issue as soon as possible, the finished machine dimensions to give a compression ratio of 6 to 1. A cylinder head capacity of 74 cc is required for this (exclusion of gasket). Will the Drawing Office please check if the tappet adjustment is sufficient to allow for the .075" increase in height. [STAMP] COPY BY/SS.{S. Smith} 103 | ||
