heater hose??????????????????? help

My smallblock chevy motor has a (extra) heater hose going to (THE BACK OF THE INTAKE)

then it connects to my heater core.

What if I block if off. Will it effect my engine cooling?

thanks.

anybody ???????????????????????????????????????????????????????????????????????????????????????????????????? ??????????/

It should`nt, but you won`t have any heater.

what intake do you have. my bb caddy has that hole but it is for a vacumn not the heater. if it is the vacumn you can block it off. I am running a edelbrock intake for the 472.

Got a picture, it's worth a 1000 words.
