1992 Chevy 3500 dually h/p

My 1992 3500 Chevrolet has a RPM Performer 350(edelbrok).My transmission is a 4L8oerebuilt. What do I need in parts to run a carburetor?Tb cable, fuel regulater, different fuel pump or is it more complicated ? I traded my 4L80e and torque converter+well over a grand for built up 700r but got ripped by a transmission shop,so I rebuilt the 4L80e not Knowing the compatibility of the TBI and carburetor fuel systems and the kickdown. Would like to trade or swap for the right kind of transmission unless it is reasonably priced to adjust the 4L8oe.I hope this Question is not stupid. Any advice would be kind,thanks Jeff Valera
