Did you change the ignition wires lately? If so, you may have cross wired the firing order of the cylinders. Check to make sure that the firing order is correct. Chevy 350's are usually 18436572, but check your manual, also the rotation direction of distributor(unless module). If that doesn't solve it, you may have a bad or loose timing chain. That's a intricate swap out so hope for the former fix! Jim

Why does my vw backfire through carb?
Backfiring through the carburetor in a Volkswagen can be caused by several issues, including a rich fuel mixture, incorrect ignition timing, or a malfunctioning carburetor. If the air-fuel mixture is too rich, it can ignite in the intake manifold, causing a backfire. Additionally, if the ignition timing is off, it can lead to improper combustion. Inspecting the carburetor settings and checking the ignition timing can help identify and resolve the problem.
Spark plugs cause the ignition in Diesel engines?
No, spark plugs do not cause ignition in diesels. The fuel compression causes ignition
What is the difference in automobile backfires?
you did't specify if it is carburetor or fuel injection.if the backfire is out the exhaust or through the intake. if out the exaust it is usually ignition and if it is through the intake/carb or the plenum/fuel injected it usually is a lean or fuel starvation...
What is the ignition point gap for a 1963 Pontiac star chief?
Through my recent searches, I have came to understand that the ignition point gap of this vehicle having a 389 engine with a 2bbl carburetor is .016. The plug gap is .040 and the distributor dwell is 28 to 32.
Why is there a popping sound coming through carburetor?
A popping sound coming from the carburetor typically indicates an issue with the air-fuel mixture, often due to a lean condition where there isn’t enough fuel for combustion. This can result from a clogged jet, vacuum leaks, or incorrect tuning. Additionally, backfiring through the carburetor may occur if there's a timing issue or if the ignition system is malfunctioning. It's essential to diagnose the root cause to prevent potential engine damage.
Why does a 66 corvair backfire through the carb?
The timing is set incorrectly. Carburetor(s) needs rebuilding (bad accelerator pump). Firing order is mixed up. Replace or adjust ignition points and condenser.
If your 1983 Ford pick-up will not start were do you start trouble shooting?
Check battery first for proper voltage. If battery is good and your engine will turn over, check for ignition spark through ignition cables to spark plugs. If you have spark, check for proper fuel pressure. If battery is good but engine will not crank, suspect either the starter, solenoid, or ignition switch. If your problem is not caused by one of these, consult a mechanic. Look to see if the carburetor is working correct, if so try putting some gas down the carburetor, NOT A LOT or you will make the biggest back fire u have ever seen coming out of the carburetor, if you put to much gas in the carburetor step back and try and start it. Do this after u have tryed the other suggestions from the first post..

It is a carburetor where the engine coolant is routed through the choke system of the carburetor. When the coolant is cold the choke will close. As the engine coolant heats up it opens the choke.
What does the condenser do on a distributor?
The condenser serves to enhance the spark by greatly increasing the voltage to the input of the ignition coil. It does this through a sudden electrical surge and a high frequency ringing effect, bringing the voltage as high as 300 volts for input to the coil immediately after the ignition points break.
