Trunk Mount Batt. Opinions needed

the hot start problem could be too much ignition advance when cranking. An easy way to test that is to get the engine to the temperature where you normally expect hot start issues. Then disable the ignition,,, pull the coil wire,,,Then crank the motor. If the motor turns over fine then you have too much ignition advance at start up.
If the starter motor drags,, then you need to go back to post # 14 and check the voltage drops as recommended.
