yes, another carb size thread

[techinspector1]

I had planned on using the air/fuel ratio gauges on the test stand when the engine comes back out of the truck for a windage tray install. I didn't know if anyone would have had a better way or not. Thanks for the advise.

The fuel line is 3/8" running through a Holley 130GPH pump w/the fuel regulator set at around 7psi.

In my opinion, you're overpowering the needle and seat at 7 psi. Edelbrocks don't like more than about 5 1/2. Are you running a deadhead regulator or is there a fuel return?
