383 in 71 Dodge Demon Carb issue?

Didn't most 383 engines come from the factory with a two barrel or a 500 cfm carter? If anything you have too much carb unless you have made other performance alterations.

Yes a 2bbl. was stock for many years. 4bbl's came with a small Carter @ 600 (AFB) or 630's (AVS)

The idle seems fine on it. As soon as you give it more gas it starts missing. Like I said the intake is a torker 383 and I read online that its an intake for higher rpms(2500-6000) and others have said to have at least 750. I believe it has a mild cam in it and it still has the single point ignition. Which I want to get rid of and put the pertronix sytem on it. What else could it be? It has new plugs, wires, cap and distibuter.

Sounds lean if it starts missing underload.

Unless one of the cylinders is down on compresion. AKA Plum worn out.
