Ls1 map sensor brake vacuum line

[73camaro]

Hey guys, I've swapped a ls1 into my 73 camaro and have a question about the map sensor vacuum lines. On my 73 camaro I have a manual brake setup with no booster so what can I do about the vacuum line that goes from map sensor to the brake booster? I have heard you need it hooked up for the engine to run right or can i block it like the other line on the map sensor?

I have done some searching and couldn't find anything. Appreciate the help.

If memory serves, the line from the MAP plumbs into a "T" of "Y" fitting located near the back passenger side of the engine. That line runs up to the throttle body (It's been a while since I have had that apart). You can simply forget about the run to the booster and plug the line off after the MAP connection or custom plumb it.
