Ee, that's a good'un.  In case the list gods are tardy in replying,
you might get a rough figure by measuring from a) top of engine to
ground, b) bottom of engine to height of skid, c) lowest point and
existing height that you'll have to pass under, d) horizontal
distance from that point to the after edge of the roof and e)
distance from front wheel to location of c.

(a - b) - c = minimum lift height at c.  If you also lift the front
end then that's your answer.  If you *don't* lift the front end then
you have to work out the right triangle with sides e and min-lift,
and then the similar triangle with hypotenuse d.
