Your caps will give you 2700 watt seconds. Not much improvement. Even both together is only one stop. But, open and trace the dircuit of the strobe you have. This is still a much bigger energy store than the filter in linear amps!

If you open the strobe you have, two points:
There might not be a bleeder, assume the caps are charged. If you switch it off, and immediately pop it, the cap charge will be small. but not zero. The current in a linear amp is an amp or so, in the flash several KAmps. Note how connections are done, and the way wires are routed. KAmps produce large magnetic fields, the wires get substantial forces. This is not the same as a normal power supply.
IThe GN is in meters
GN 160 isn't bright enough for F64 at any reasonable distance.
Typo?
Jim,
Thanks for important information, you are right about the energy of my capacitors isn't enough. Tim is right, I would need a small nuclear blast. I would have to get 50000 uF at 400v to give a little bit more than 5000 w-s. Even with an efficient reflector pointing straight without any diffusion it will impossible to get my f64 with a 64 ISO film.
How did the photographers do 40 years ago shooting 8x10 low speed color films? High power flood lights??
Will your subjects be wearing welding goggles?
This thread gives me a head-ache. There must only be about 6 people in the world who are LF photographers AND understand what you're talking about. Oh yeah...there's the six of them. :=)

They didn't shoot single-flash at F:64.
Instead of one super flash couldn't you use multiple smaller flashes?
OTOH Forget the googles and go with a full face sheild.
