Who will sell me an original 1923 piston?

[alsfarms]

I am closer to a rebuild on my 1923 Dodge Bros. I do have a couple of questions. Depending upon the condition of the cylinder walls, how much of an over bore can this engine take? I would like to have an original piston to evaluate before I even crack the head off my engine to consider the use of Ricardo head. Next question. Does the stock piston, being flat top, come flush with the top of cylinder block or does it protrude into the combustion chamber? If anyone has an extra piston to sell or even loan, I would appreciate your getting in touch with me.

Thanks,

Alan
