Where would be a good place to get the best vacuum signal for my gauge? I "wanted" to use the port on the back of my intake but the fuel inlet lines block access to it. The only way to get to it is if I use a carb. spacer but I don't want to do that right now.
Could I use the small vacuum port on the front of my holley as a reliable source?
I want to get a vacuum reading during full throttle to see if I have the best power valve or not. Right now it's a 6.5
