Measuring vacuum...
Dark,
Where are you measuring your vacuum at?
We have nearly identical setups N/A and I have 10-11 inches of vacuum at 750 RPM idle. Measured at the fpr and at the GT40 tree under the plenum with a vacuum guage.
I am going to measure it at the big barb too for ya. I'll post it in a minute.
I agree with the pic idea too. That might make something jump out at everyone.
