A Thunderbird with the V8 has 330 pounds/inch rate springs (except Sport, which is around 400 if what I have read is to believed, which is what one set I did was).
a 97 camry has 120 pounds/inch rate springs (just used as an example, one that I found numbers for).
EDIT - I guess they are progressive, so the first inch compresses at 270 pounds, and goes up, but still they are pretty hard to compress.
If I remember correctly, and I probably don't, it looked like over two inches to compress it enough to get the upper mount off. That was 660 pounds required to compress it, and it might have been more than that. A co-worker was able to put the strut/coil assembly of his Scion xA on the ground and use body weight to compress it and use zip ties.
