      How to find TDC on BBC

      What is the easiest way to find TDC, In the old days i remember sticking a screwdriver down the spark plug hole on the compression stroke and when it was at the top that was TDC. But with this BBC the spark plug is not at a very good angle to do that. I do have timing marks on the dampener from 0 to 60 and a mark the builder drew on around 32 but im not sure if thats a timing mark or TDC?
