Trying to validate a distributor. On the C5OF what is the specification for maximum distributor advance and at what distributor rpm does it occur? Thanks.
A C5OF-E uses the 13/18 reluctor. If it is assembled correctly, the maximum mechanical advance at the crankshaft will be 2 X 13 = 26 degrees.
Thanks for the reply. Second question is at what distributor rpm is the 13 degrees achieved?

From the Ford Spec sheet
C5OF-12127-E
650 RPM - 2 1/4° to 3 3/4°
750 RPM - 4° to 5 1/2°
1,000 RPM - 6 1/2° to 7 1/2°
1,600 RPM - 7 1/2° to 8 3/4°
2,000 RPM - 8 1/4° to 9 3/4°
Steady advance from 9 3/4° to 13°
At some point around 2,500 RPM the distributor max advance is 13°
The limit is 14°
Those numbers are distributor machine numbers

IMO no way the curve results will ID a distributor. Most of the ones I work on have been messed with.
It is a C5OF My question was to validate it is operating to specification. Thanks.

Agreed on both counts.
