Big Problems with New 408 +PICS

More info:
-All lobes are fine, measured and at spec. Lifters all fine.
-Pushrods are straight, all checked for unique signs of wear, nothing noticed.
-Smoke only started after second run on strip, about 150 miles on engine. Only on strip is seems.
-Head are out of box, not re-torqued but checked before disassembly, OK.
-I reviewed the video I have from the car on the dyno and on the strip, seems that the smoke comes from the exhaust after he let off the gas.

One thing that I did find out:
Oiling rocker arm shafts were installed upside down, so the oil feed hole on my Comp Pro Magnums were facing down instead of up and toward the intake.
