What is Hole on Front of Intake For?
Got my intake back from the powerder coaters but they left a cork (I think) in a hole that's in the front of the intake, below the 3 holes for the throttle body. Does a bolt go there to block it off or is it for a vacuum connection? You can see the spot in question in the picture, it's the painted round part down by the bottom.

No. In the 95-97 LT1's that is where the PCV valve vacuum line connects. In the 94's, it is plugged with a pipe plug. Not sure what, if anything was attached there in the 93's.

He's not asking about the open, black hole right below the throttle body bores. He's asking about a hole about 2" below the TB bores, that has a cork in it, and is covered with powder coat, making it almost invisible in the picture.
