Hey guys not sure how 8 volt battery came into it, I have a V8 flathead motor, I have a 6 volt battery that I am working with all of your suggestions are good so I am going to: 1) up grade cables to "O" strain welding cable for flexibility 2)by pass disconnect switch 3)add a grounding cable from starter mounting bolt to frame I let you know what happenes

Here is how you can check out your starter circuit and cables. All tests are made with the starter operating and the ignition switch OFF. Connect the POS or + lead of your voltmeter to the cable connection on the starter and the COM or - lead of the meter to the NEG post of the battery. You should read .5 volts or less, while the starter is operating. If the reading is higher, you have excessive resistance in the circuit. The resistance can be caused by cables or the starter switch. To isolate the cause, check the voltage at the input to the starter switch, it should be less than .1 volts. If it is higher than .1 Volt, your problem is the connection to the battery or the cable. If the reading is less than .1 volt move the meter to the other side of the starter switch and repeat the test. An acceptable reading would be .1 volt higher than the previous test point. The ground circuit is tested the same way, except that the meter leads would be reversed and the maximum reading at the starter is .1 Volt. The 36 has longer cables than the later cars and it is very important that the correct size (0 gauge or larger) cables are used in the starter circuit. If your readings are within specs and the starter still doesn't crank the engine over fast enough, check the bushings for side play, the commutator and brushes for proper seating and cleanliness. You can also have the starter checked for proper current draw by someone who has the proper equipment.

DID YOU TRY, turning the engine over by hand with out the starter to see if it is tight,to rule out the battery and starter, and the grounds, if it is tight it does not matter how many batterys and starters you have,,,you have to break in the ENGINE FIRST,!! if you can get it started, let it run for a hour,or more,,,, just keep a eye on it, USE A HOUSE FAN on a step ladder to aid in cooling,and keep checking it, I had a MODEL A, that I had to pull it to get running, but once started and broken in it was no problem after that,we used a rope and other car to pull it and used second gear, HOPE THIS HELPS,37RAGTOPMAN ,,and KEEP ON TRUCKIN,,,,,
