I revised my statement since 1000 F is a bit high, but I still wouldn't bother unless I had at least 400 F.

The series capacitance would not be less than the rated 350 F, unless you are accounting for the fact that only a fraction of it is usable due to voltage drop. The series configuration increases the voltage capacity to > 14V so that it's usable in automotive applications.

EDIT: The above statement about series capacitance is incorrect. The farad capacity does drop with each capacitor added in series due to a charge plate being effectively canceled out when the series connection is made.
