How many volts needed at a starter

This is on the Buick (300-4V Skjylark), but same theory should apply.

I get a good strong click from the solenoid, then absolutely nothing as far as turning the starter motor over. I'm seeing some big voltage drops, but don't know if they are too much.

12.2V across the battery posts
11.0V at the back of the ignition switch
9.5V at the fuse block during crank
8.25V at the S post on the starter during crank

If I hear that 8+ should still turn the starter over, I'll open it up and clean the ring.

TIA
Loren
