Have you checked the compression? The symptoms that you describe can be caused by an ignition problem, but can also be caused by low compression on one or more cylinders. Bad compression can be caused by a blown head gasket, burned valve, cracked casting, cracked piston, or broken rings, just to name a few. The miss and/or shake can be just as much with any one of these as with a bad spark plug or ignition wire.

You have helped me in the past so I figured I would give it one more
try. I have a 1965 Chrysler Imperial Crown Coupe that has a miss and a
shake only when I am in drive. I have changed plugs, wires, dist. Cap,
rotor, and set points to 17, and timing. The carburetor has been blown
out extensively but I continue to get the shake and the hesitation as I
accelerate on the gas. What am I missing? Please HELP!

I agree with the gentleman that stated the battery cable could be the
issue because I just fixed the exact same problem I was having with my
65 Imperial. And to the others that responded you would not be able to
jump it from the relay that it totally incorrect, it can be jumped from
the relay or the starter.

I agree that it's not the battery or cables if you can jump the relay.
Is
this vacuum switch a 50's thing? I've never heard of them, but all my
cars
are '70 and up.
