Atomic, look into CPT transmissions. He usually does F body trannies, but its pretty much the same thing. And they are the best of the best IMHO, don't spend $2K on a tranny that will just let you down, get one built by him and you will not have to worry about anything. Also you will need a good converter and he could hook you up with that too.
But when I got my 95 Camaro the tranny was perfect, shifted awesome, chirped the tires going into 2nd without any tuning or shift kits. Then I blew my motor and went from a completely stock motor making about 265 RWHP to a motor that puts down 430 RWHP and my tranny lasted less than 3k miles before it gave up. I could still drive it, but I couldn't go more than 1/4 throttle before it would start slipping. I was going to have frank at CPT rebuild it, but got a good deal on a 6 speed, so I swapped it from auto to manual.
Buy the supercharger, but you will get addicted to boost and start pushing your luck shortly after installing it. Then you will burn up a set of pistons, or start breaking rods, the tranny will go and you will be really dissapointed. Well thats how I get. I just don't want to see someone give up on a project because it started breaking shit.
But I'd say get the SC and install it, but be smart about it and don't start turning up the boost until your ready for it. Also if your still TBI start looking into multi port injection setup, you will gain alot from that, especially with boost.
