Welcome aboard!!!!!! Thanks for signing up 
Well, the 4.9l STS (1992) has basically no aftermarket, and the 93-95 has limited aftermarket, and 96+ is about the same, except there really arent any chips available...... Most people that have mods have their equipment custom..... I dont think there is anywhere you can buy a supercharger that wouldnt be custom...
I am no expert in whats available, others will chime in whats available.....
