69 Charger 440 with electronic ignition conversion. I had a miss and pulled each plug wire at the cap and had no change in idle on cylinders 1,4,6 and 7. Carb was just rebuilt. ??
1,4,6,7 all feed on one side of the dual plane intake. Either a massive vacuum leak off the intake vacuum port [try capping it], or carb is plugged internally.

If you have power brakes, this connection has bit me more than once when the booster failed and turned into a vacuum leak.
Did distributor work fine before the carb build? If so, last change was the carb and worth checking out. If the conversion was recent to electronic too, then make sure not a Chinese poor quality one. Recently had one that missed fired a few cylinders. Had to change the pickup to original MOPAR and a new reluctor to fix it.
