Default 99 bbc efi can i convert to carb

i have a 99 chevy truck 3/4 ton with a 454 efi engine. im wonder what would be intailed if i wanted to convert it to carburator?

i know i would have to change the manifold to the carb style and get the carb, but what else would need to be done?

Do that, and you'll never again be able to register it in Ca.

A. Scrap the ECM, and get a regular distributor
B. New intake to go with the new carb.
C. If it's got an automatic, new transmission.

If you run with a carb, the pcm is history. Time for a TH400. Not sure about the gauges.
