I have a 1977 dodge w200 with a 5.2L V8, I put a custom intake manifold for a 4b carburetor on it but it misfires now. I’m not 100% sure what it is, I can’t use a diagnostic test to test it since it doesn’t have any new technology. Please help asap

If the problem started when you installed the new manifold and carb then that's the likely cause. Start looking at issues like vacuum leaks or a problem with the carburetor. Check spark plugs for clues as to whether the engine is running too lean or too rich.
