Do you have any converter slip info? The best info would be driveshaft RPM from a data logger but if you are sure of your RPM and MPH at the light you can also figure it out that way. When I figure it out I get 35% slip based on 6700 rpm, 112 mph, 4.11 gear and 32 inch tire.

A 5.0 gear with the same 32 inch tire and 6700 RPM would end up being 115 mph in the lights with 10% slip. So you either need to talk to your converter mfg to see what they say, or just try it. If the converter tightens up that much then you'll be golden, if not, you'll need to buy a different converter.
