Vacuum line on the Exhaust manifold/y-pipe?
Hi there..
I am in the middle of an TPI swap on a 1987 Camaro. Carbed to TPI.
I have a Vacuum line going from the y-pipe more close to the passenger exhaust manifold...Where should this be connected?..I have forgotten how it was on my carbed engine.

The carbed engine had an EFE valve, which the TPI engine won't have. Instead, between the manifold and Y-pipe there'll be a spacer instead of the valve. There a pic in the following link:
