tbi conversion

[oneoffusa]

I have a 92 gm 454 with tbi. Unfortunately Edelbrock has discontinued its conversion kit. Are the parts available individually? If so, is there a [;ace to get all the part numbers? I am refreshing the motor, and would love to get rid of that heavy manifold and crummy tbi. Any suggestions? It has the electronic controlled tranny,so a complete replacement of the efi with another ecu is not a economical plan for me.
thank you
