Does it smoke constant, or just when you let off the gas ?
Pull the plugs from the side that is smoking,If the the two center plugs are fouled, I would say that the intake is leaking, If it is the back cylinder that is fouled check the trans modulator valve the smoke may be tranni oil, or brake fluid from the power booster, You should notice these levels are down, and may have topped them up recently,
If all plugs are rusted and very clean it may be antifreeze.
Is this smoke only there when you start the car as my 68 will smoke one side untill it warms up and the heat riser valve opens, The smoke I see is only condensation, after it gets hot no smoke at all.
Check the heat riser for proper operation and that it is not stuck in the closed postion.
