IIRC, its for the brake booster or vacuum port.

Re: GMPP TBI vortec manifold question.

The EGR has its own port for the valve in front, as well as a port for the exhaust gases in front right about the #1 Cyl. I think it's for the brakes. I'm running the brakes off of a line from the t-body right now.
Thanks guys
