Quick questions about PFC calculations

Hi all,
   I've never worried about power factor correction in a NST powered 
coil, but I got this great lil 9/30 (Thanks again Hal) and thought it 
might be cool to run it from my car via a 400W inverter that I 
have.   I know the inverter would not like an inductive load.  The 
instruction said I should probably run a resistive load at the same 
time if it acted up, but I would think power factor correction would 
be the way to go.
   My question is:   Did I calculate this cap correctly?   First I 
get 270VA/120V = 2.25 A, then dividing 120 by 2.25 and get 53.333 
ohms.   Now measure the resistance across the primary I got 2.2 ohm 
so I assumed the impedance due to the inductance is 51.1 ohm...the 
difference between the calculated and measured.  Then using XL - 
Xc  = 1/(2*pi*60*51.1)  I got 49.7 uF.
   Am I on track here?  I am assuming the cap would go parallel to 
the input, but please correct me if I am mistaken here(thinking anti 
rsonant LC circuit).
Thanks,
Mike
