The cam out of the ECZ 6015B block had these letters and #, YB1 behind front journal and RYB 10 stamped on the rear journal. Anyone have an idea who manufactured this cam and what the spec's might be? Thanks Ted and Marv for the response on my previous question. I found some other letters on the rear journal which are; G08 with the letter m inside the 0.
