Recommend me a converter for this 273 - 727 combo

Recently a fellow mentioned Hughes is making him a torque converter with the old size specs. for the same price as a new style converter. I have used Hughes converters and they seem to be good converters and are reasonably priced but the only thing is they always (in my experience) seem to be a little tight on the stall speed spec. In other words if you order a 2500 stall it may only stall 2200-2300 rpm. With that in mind you may want to order a slightly higher stall than wanted.

Fishy you are right on the money. I bought a used TCI Street Fighter converter and TCI advertises it to stall at 3500. I called TCI and they said that the converter will stall at 3500....but that it would only stall that high behind a very strong 360. When I described my mild 360 build to them the tech said that in reality I would only be looking at about 2800 stall. I have had several aftermarket converters through the years and I have yet had one flash to the maximum advertised speed, they were always short of the advertised stall speed .
