1967 Impala SS427 L-72?

This is what happens when you have no documentation.
Once he restored the car, he lost any chance of proving it came the way it sits. too bad.

This car kinda reminds me of stories of what I heard about some old chevys being built in the janesville wisconsin plant. One guy told me, there were some pickups that had their engines swapped out while inside the plant. So there are some odd trucks running around with highest performance engines (that would have never came that way). Some signs would be left behind of the original build (lets say like a wrong trans mount). They would not have changed the build sheets either. But some of these '427' and '454' trucks made it out the door (perfectly date code correct to the vehicle). Some folks looked the other way. and no vin would be on the block (obviously). It just makes me wonder if this happened here on this impala (not a true factory sanctioned build).
