To give you an opinion on your question, I have a 37 Ford (relatively stock) with a 4.11 rear end and Columbia. When in overdrive, the gearing is slightly under 3.0. I can easily start on level ground when in overdrive and have for over 20,000 miles without clutch change. If it looks like a slope, I need to get out of overdrive (before stopping). With your light weight and expected 3.27 gearing, I would think you can start from some slopes with ease, but not from a dead start on a good sized hill (5% grade?). I'm sure others will disagree.

I also have a 39 Ford with 3.54 gears. It easily starts from a dead stop on any Iowa hill I have been on. Both cars are a lot heavier than yours.
