azlkk Your 35 original stock V8 Ford will operate very well with an Optima battery provided the third brush in the generator is set down low with about 3 amps charge showing on the dash ammeter whilst driving in daylight (no lights on). Remember the third brush system is not a regulator and does not compensate for any electrical loads switched on or the charged condition of the battery. The only thing special about an Optima battery is the type of assembly of the plates, it is still a lead acid battery. Bear in mind also that the ammeter shows about 3 amps current draw of the ignition coil which means with about 3 amps charge showing on the ammeter then the generator is outputting 6 amps. Dont fall for the trap of setting the third brush at 15 or more amps because you will cook the battery. The original drivers handbook that came with the car when new will give some information on setting the third brush. Just remember, keep it down low. Regards, Kevin.
