    1984 k5 Blazer with 350/700r4 with fresh rebuilds on both, I have a nasty shake at or around 45 mph. Could it be u joints? Tranny? It did it with the old 305 as well. Tires are new and balanced.

    could be a bent or unbalanced drive shaft. check with your local shop to see if they can test it.
