Hello everybody!!

I had a Recent rebuild on 3.2l engine. I have ran it for about 45 min. and it looks like a lot of smoke. How much smoke should be expected before it breaks in. Usually clean until warm up. Before I go out on the street I want to make sure I dont make things worse. Any advice or other. The shop that reuilt it says its not unusual but this seams a bit much.
Thanks for any thoughts on this.
