I need a clear picture of a holley and all the lines coming off of it. i took my edelbrock off and i dont remember where everything goes on this one. Mainly the vac lines and one bigger line on the pass side
The big vacuum port would be for power breaks.The small coming out the base will be manifold vacuum for something like the trans vacuum modulator or whatever need manifold vacuum.The port higher up will be ported vacuum used for a vacuum advanced distributor.
