What stall for TH350?
Indeed from what you have posted, if you are looking for better 60' times then you will want to change the gear ratio at this point. I would suggest that the converter restall is only going to leave you dissatisfied. With N2O you are going to want a "tighter" converter generally speaking. I know that it is only a 100 shot, but that power adder does push the stall and can cause you to "blow through" the converter.
By virtue of changing the transmission you have raised the 1st gear ratio. I think if you were to go to a 3.7x,3.9x or a 4.10 ratio you would see improved 60' times.
