oil fill tube on intake manifold-is it original?

[JST69Z28]

Attached is a photo of the intake on my 1969 Z28.  Question:  Is the oil fill tube original?  The block is not original, but the 1974-1978 owner told me he had the engine rebuilt using all original parts except the block.  Intake part number is 3932472.

No.

For '69, small blocks had an oil fill cap on the LH rocker cover. The hole for the tube on the intake was plugged.

Correct for 67 and 68.
