Crank Shaft - Racing C Mod - Mark 30.  Beveled MK30 crank - small taper.  Has some pitting on #2 & #3 journals and some on lower journal center main and a little on lower  reed cage journal.  Not bad.  I would use this crank in my own motor.  All & all still a good crank to run.  It's hard today to find someone who will bevel a crank.  1 Available
