What color smoke? New motor, what are you doing flooring it? That could be part of the reason.

If ya used file fit rings maybe ya just made them a little loose thats of course if the smoke is blue, black smoke you probably just have a rich mix I know with the 950 carb on my 408 I am making a little black smoke at WOT. For a better read on the situation I am sure everyone here could use some more details about the engine and color of smoke.
