Voltage drop at fusebox- 69 camaro

Having some issues with a new hi torque mini starter not getting enough voltage to adequately engage and turn motor over. While tracing, realized I am only getting 10.8 volts at the fusebox (at any location). Battery is brand new and pushing 12.9 volts. I am familiar with the resistor wire for the ignition, but could there be a resistor wire from the battery to the bulkhead connector? Or do I just need to trace the main wire to the bulkhead and look for corrrosion/voltage drop location? Thank you.

Check voltage at the bus-bar on the horn relay as it is the main power distribution input to the fuse panel.
Also check connections at the same location for the fusible link, if it is crunchy it should be replaced and the
main splice. Then the main junction block (behind the battery) should be inspected, as well as the battery cables and connectors.

voltage at bus bar is full as is the junction block. It has to drop somewhere between bus bar and fusebox.

Check the condition of the main lead from the bus-bar and then follow it up the fender skirt to the bulkhead connector. Look for any splices and cuts.
Then inspect the bulkhead connector itself for any damage. It should be tight against the firewall. Failing to find any issues out there I would carefully remove the panel inside and test at the connection at the rear of the fuse panel, it is is 12 there, and 10 on the other side look for rusted out or other seriously corroded connections.
