That is a replacement dist.

Orig was 0231-115-065

T his should be a vac retard dist.

4500rpm-43\3000-31-37
Idle-2.

To make sure this new dist is vac retard, start the car and at idle, check timing w/strobe...then disconnect the vac line to dist and see if the timing goes higher w/o vac, and rpm should also increase.

Replace vac hose and it should retard again.
Do this test w/o stopping engine
