Need '62 300 HP spark advance map data

[Duke W.]

If anyone has a ST-12 or '62 AMA specs handy can you give me the centrifugal and vacuum advance data for the '62 327/300?

Thanks. I am assuming the centrifugal data is disributor degrees and RPM, so nominal at the crankshaft:

2 @850
18 @ 3200
24 @ 4600

This appears to be the same as '63 as is the 201 VAC.

That is correct.
