Default 1967 Impala 283 running REALLY rough
A little wisdom is appreciated... My '67 Impala Convertable is running really rough. It has 116k original miles and never rebuilt... Replaced plugs, wires, dist cap, carb. Not sure if it is timing, compression or a valve thing at this point. No backfires, and the fuel pump works fine. Any thoughts are appreciated. Thanks!

So, this problem started before you replaced these things, and no change? Did you replace the points?

Might check the wire from the coil to the distributor too. They tended to get kinks and loose contact at the entry to the distributor.
