I have a 6bbl set up on the 440 in my 69 RR. The car runs great with plenty of power, but I am wondering about the set up of the vacuum lines. There is no vacuum advance hooked up to the distributor, and that is part of the reason for this post. Below are some pics of my set up and a set up that I pulled off line. There are some differences in the way the vacuum lines are hooked up. This is a picture that I pulled off line. the vacuum line running the advance on the distributor is coming off the top of the middle carb. The vacuum running the outboard carbs is coming from below that. Here are my carbs...The vacuum running the outboard carbs is coming from the top of the center carb. There is no additional vacuum port on the carb to hook up an advance for the distributor. Lastly...here are two capped off lines coming out of the back of the intake manifold. should these be connected to anything? Any advice on how to properly set all of this up will be greatly appreciated.
