Well I have to say to the people who were interested in the cam I had for sale,that I am sorry........I have now been told by the buyer that it is a "re-grind".....I was going by what the P.O. had written in his manual,he had a list of installed parts.Some were obvious,the names were right on them(Lockhart,Dyna,Lester)....I did specify in the post here that I did not know for sure if it was a Yosh cam or pistons,......didn't Hope have a post going about "If you don't know it for fact"..............any way I have always felt that if I f@@k-up I should admit it..............so I f@@ked up ..........sorry
