Also are you planning on using an OD automatic, or not? This will have a huge bearing on the rear gear ratio...
Anyway, assuming the stock 5.3 and using the tranny from the Tahoe, the stock converter will be tight- but that's not necessarily a bad thing for a stock engine, especially when you consider the cost for a good torque converter opposed to using the stock TC.
If max acceleration is your goal, there will be something to be gained by a slightly looser TC and =/>4.11 rear gears. The stock TC will have a lower stall speed in your lighter Bonnie, especially if the gears are lower (higher numerically).
