So I have an AMC 360 with a Edelbrock non-EGR manifold and Holley 4160 carb(80457S). It would always hesitate when stepping on it to WOT. I took it to a friend's garage and one of his older mechanics looked at it some and disconnected the vacuum line from the distributor and it runs better now? The mixture was a little off he said and the timing a hair off. He adjusted everything and plugged the vacuum line coming from the "timed vacuum port". So now I am running with nothing on the distributor vacuum port....Is that ok?
Anyone have any insight here?
