I got #60 jets in my primaries, can't even find these unless order directly from Holley, and even the Holley kits start at #64. Secondaries get #62 jets, and are delayed all the way to 3/4 throttle, so unless I really floor it they don't even crack. Really, the secondary opening motion is a pretty much 1:1 copy of my Q-jet, somehow i wasn't too happy with the secondaries opening at 1/4 throttle. My power valves are 8.5 primary (half the idle vacuum, which is 17"Hg) and 6.5 secondary, may go down to 6.5 primary and 4.5 secondary tho, test driving will show which is better combo. It's definitely not yer typical double pumper, and I'm firmly determined to make it hit the 15mpg mark

By the way, that may be a real dumb question, but if the engine runs lean all the time will it still be a gas hog? I never see black smoke coming outta the exhaust, so I can't be running too rich, yet again the fumes have a pretty sweet and heavy smell to them...
