Yes, your request is meaningless without this number.
Having said that, you have 2 strikes against you. Trying
to pull an oscillator that wasn't designed to be pulled
is a problem. Secondly, the circuit you described works
in so called "parallel" resonant mode. For optimum pullability,
you want "series" resonant mode. Do yourself a favor, now
that inexpensive VCXO's are available, patch in one of those.
