Bill's question and suggestion to clarify was pretty insightful then. I suffer from the same handicap as you: short legs/ long torso. (6'2" w/ 87 pbh in my case.)
Knowing what I now know after many years of figuring it out, I'd suggest making sure you get the biggest frame you can possibly stand over. Especially with the older models that tended to have proportionately shorter top tubes. They might still only be marginally long enough, but the good news is that there was likely a size increment that worked pretty well. The later, expanded-sizing models don't come in as many increments, but the good nees here is that if you DO happen to find one that maxes-out your standover height it is likely to be the most no-compromise, best-fit bike you've ever owned. Just don't settle until you find it.
Also, FWIW, the very first run of sam hillbournes (canti versions in metalic orange or sagey green wihout creme headtubes and with gold decals, I recall), which were among if not THE first to use the expanded sizing, had longer top tubes than later versions. Im always on the lookout for one of those, even though i don't "need" one.
