My '54 235 has timing marks on the front pulley. It doesn't have the indicator tab on the block, so it isn't used for timing the engine.
I've always wondered about the pulley. I assume that a previous owner installed the pulley. I've never had the engine apart so I don't know anything about the pulley. Don't know if the marks are in the correct location.
These pics were taken from passenger side looking down so the numbers are upside down. Numbers go from "0" to "40"
