well after much personal debate, I have settled on a Corvette high-stall converter. I thought it would be the best all-around for my car specifically, and it is also much less expensive than a higher stall. If anything, I believe that I erred on the side of caution, which is better than erring on the other side. Now the shop can finally get to work on putting the transmission back together. Hopefully it will be back on the road in a couple of weeks or so.
