Exhaust leak sucking in air causing big boom back fire. Or smog pump and one way valves are not working properly. Air pump belt missing? Custom chrome airfilter with exposed aircleaner? Burnt out glas-pak mufflers? And some rumbling poping is normal when the throttle is suddenly closed shifting thru the gears.

if you have the skill you can do it yourself.It seems it is a timing problem. The back firing is cause by an unburn fuel, therefor it could be your contact point, either you have to change it or clean it. You have also to check your rotor and rotor cap for proper contact and the spark-plug for proper igniting, maybe it also needs cleaning or replacement. If you can't do the said check-up and work, better bring it to a shop. A professional mechanic is a must in this kind of situation since testing the functions of the different parts is essential.

need more info to tell you more info but hear gos a good gees win it back fires is it thew the carb or the exhaust if it is thew the exhaust you can retard the timing a Little it will help but if it thew the carb get the tool out because it is the time chain is stretched and it is firing on a open valve. to retard your timing if you do note no let engine worm up grabe distributor and turn it back to the fire wall that is retard to the radiator is advance turn just a little no more than 1/8 inch back. you may have to loosen bolt under distributor to turn

it's a simple system...I'd look at the plug wires. One way to check them is to start the car at night and open the hood...look for any arcs across the wires

A worn out muffler could be causing it. It could also be caused by the engine's timing.

You can afford a Vette, but you can't afford to take it to the shop??? Maybe you should trade it in for a Toyota or something you CAN afford!!!

Try a more premium grade of fuel.

You probably have a timing problem.
