We wish to rig up an apparatus for investigating valve bounce on the Phantom engine and suggest we use an assembly of scrap crankcase top half, cylinder block, and head for this purpose. Will you please arrange to have the head and crankcase top half divided between the third and fourth cylinders so as to leave the fourth rocker shaft bearing and the fourth camshaft bearing in the front portion. Will you also modify the camshaft to HR.77 and have made the following pieces :- HR.78 - Spider for flexible drive. HR.79 - Adaptor for oscilloscope drive.
