So I've been thinking about adding a new torque converter to my Z28, but I'm clueless on this subject. The car is basically stock and I doubt I will go much further than bolt-ons since its a daily driver. I dont plan on racing it but I want to be able to launch with a little more authority and it'd be nice to be able to stab the throttle and break the tires loose at 30mph. I just dont want to have to rev the hell out of it to get it going when I'm putting around. So would something like a Vigilante 2800 get me what I want? And how different is driving a car with just a stall than a stall+shift kit? And what "size" will fit a stock 4l60e..9.5"? What do I need to be looking for?

 

Contact each manufacturer of aftermarket torque convertors,tell them your needs,and after getting responses,average the reply information and that should suit your needs.Every reply will/would probably be different in stall RPM,stall torque ratio,and convertor diameter.Averageing all the return data would give you a good starting point for deciding.General consensus of forum users is go higher than what you think you would like.
