CAMSHAFTS TO RUN WITH LARGE TAPPET CLEARANCES. We understand from Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} that the long toe camshaft for P.III. to run with large tappet clearances is now on test. The camshaft which has already been instructed for Wraith III. has standard 25/30 toes, and we are awaiting result of the tests on the long toe camshaft for P.III. before deciding whether to instruct a similar shaft for Wraith III.
