I have a C5AE-H 427 S/O Block. I am trying to figure out what I should set my dual-point to. In a book I have my block number pulls up as a 65-66 427. So when I look up what my dwell angle should be I get as follows.

1965 V8-427 Conventional ignition 30-33 deg. Transistor ignition 22-24 deg. I am assuming mine is conventional being that it is a standard Ford dual-point?

1966 V8-427 22-24 deg. dwell angle.

So, any ideas as to what I should set my dwell at? I am checking them using a dwell meter. I am not blocking off one set of points then checking dwell. I am checking them together as a combined dwell.not

Thank You,
