Any ideas on how I can get a manifold vacuum reading on a SBC with an Edelbrock Torker and a Holley 4150HP? There are no vacuum ports...

I need to determine if I have the correct power valve installed and need to know the vacuum...

Is this just a stupid question or what?? Maybe this is an example of not being able to see the forest through the trees?? Heck, wouldn't be the first time...

How can I get a manifold vaccuum reading without any vaccuum ports?? I was contemplating creating one in my 1" spacer?? How do you all determine what power valve to use??

Not a stupid question at all.
Sorry I missed this post earlier.
I usually install a port in most baseplates so that racers don't have this problem, but it's also fairly easy to put a small in into your intake, too. Just a drill, small pipe tap and a pipe fitting with a hose nipple on it, which can easily then be replaced with a pipe plug when not in use.

Hope that helps,
