intake manifold vacuum ports
I have a Street Dominator intake manifold on my 350 motor.
There is a small vacuum port behind the carb. Well strange as it seem the motor semms to run a little better with the vacuum port open.
Should all vacuum ports if not used be pluged or can they be left open.
Seems to me you would loose some vacuum with it open, but the car at least idles better with the port open. Barb.
