Blue= oil.  (but everyone else already answered that !) 

THose "400 miles"  that are on the "new" engine - are they good, solid 
"highway cruising" miles or just short trips  out and about ? The reason 
being is that your rings ( I'm assuming you replaced them....) may not be 
seated properly yet.  Take it out for a decent long drive & see what happens. 
  

Who assembled the engine ? shop or you ? Hopefully it was put back together 
with the gaps in the different rings NOT lined up ! Have ya changed the oil 
yet ?  Assembly lube running around in there could be causing some of the 
smoke also. 

Also of note: I don't know what is available for the roadsters these days, 
but you didn't let some parts guy talk you into Moly rings didja ?? ( a good 
machinist can make anything fit if he puts his mind to it)  Moly rings in a 
typical road car will never seat quite right. They're for "extreme" 
conditions only.   Next item while we're at it..... NEVER ever EVER !! put 
any sort of "wowie-gee-whiz" teflon (ala Slick-50) super lubricant engine 
additive in a fresh motor. Again... the rings won't seat!. (SLick 50 used to 
recommend at least 30K miles on a car before adding) 

Just some thoughts... now go drive your car !
