Default 78 Bronco backfires thru the carb

Well, I bought a 78 bronco. The engine is either a 351 of 400. Depends on wheather I listen to the po or the vin tag. Anyhow the engine has a 2 barrel carb, a full MSD ignition(distributor, coil, wires, box). About a week ago it started to backfire thru the carb. It usually happens after I shift gears at lower rpm's. I don't know much about carbs or tuning engines with them. Any advice y'all can give me will be greatly appreciated thanx guys.
