I am sure I know what the answer is, but want to double check. I am replacing the 3 x2's with a Edelbrock. Previously I did not run vacuum to the distributor - 57 and later type - but I am going to hook it up to this carb. The instructions say one side is for "timed" vacuum and the other is for "full" vacuum. Which one should I use? Thanks
