Make sure your U joints take grease in all 4 caps if they are greaseable! If they are ungreaseable you will have to press them apart and lube each cap by hand and reassemble or replace. You will get just the symptoms you described when a dried up U joint starts to bind and fail.

Especially after you said the engine idles and revs up smooth. A friend of mine was just telling me last night about a 64 Plymouth wagon that his Dad bought new and had a vibration in it. After many trips back to the dealer they discovered the pinion angle was off right from the factory.
