If there is a exhaust leak anywhere in the exhaust system it will make it back fire out the exhaust. Also raw fuel being in the exhaust pipes will make it back fire too.
That is if it is back firing when you let off of the throttle. But if it is back firing when you give it gas that could be bad plug wires are spark plugs, Timing may be to slow. Cam lobe worn down, Not getting enough fuel. could be a # of things. Check these things first, and if you still have a problem, then ask your question again.

What causes a 1973 Pontiac 350 engine to backfire through the exhaust?
A large backfire is most likely caused by a bad spark plug or plug wire. Unburned air and fuel pumped into the exhaust will often be ignited by the other cylinders still burning exhaust gases. Also check your ignition timing, if it is late and you have a rich mixture you can get a backfire. An exhaust leak will let air enter the exhaust under deceleration and cause a "popping" sound.
