At 60Hz, that's 276 uF. 330uf 600VDC caps should work. I'm not very
confident with my crude approximations. Therefore, I would feed the
model to LTSpice and see what it's really going to do.

You're charging to the peak values, not RMS, so it's going to be 680
volts at a minimum, and probably more like 750 for some margin of
safety.

Caps of that size and rating will end up costing as much as the coil
itself.
