It's fairly common with a new engine as the piston rings begin to seat. The thing about cylinder walls is that they have to be smooth to seal correctly. A new engine has very rough surfaces on the cylinder walls that hold a lot of oil that the piston rings cannot get to (wipe away). Give the engine 1500 miles to get a bit of glaze to the cylinder walls and then see where you are with the smoke. It can also be valve guides or seals (I know you had them redone......)

Does your wait to start light come on and go off? Does your fuel pump turn on (you should be able to hear it run for 20 seconds when you turn the key on)? Does the tachometer needle move while cranking?

Let us know what you come up with on the WTS light and fuel pump and we'll go from there.
