Ok, one more question on the Holley jetting.

Ok I took it out for a drive and paid much more attention to what and when with a vacuum gauge on it.
I have 15in of vacuum at idle with a 14-15 AFR, and 10 at the light throttle cruise where it shows in the 10:1 range.

#72 jets in the mains 6.5 power valve, and at 1,200 rpm's it goes rich and stays about there until I get into it to about 1/2 throttle then it shows 12.5-13 AFR as long as I have that throttle opening.
If I back off on the throttle any it starts going rich again until I hit the idle stop and then it comes back to around 14-15 again.

WOT shows 10's also even though I jetted all the way down to #66 jets in the secondaries.

No matter what speed or what gear I am in it shows 10's in the 1,200 rpm range.
And as I said it shows 10's at WOT even with #66 jets in the secondaries.

I'm going to make absolutely sure the secondaries are opening here in a bit with a paper clip on the vacuum diaphragm rod.
