I'll have to jerk around with Holley, maybe I can get them to give me a 390 for a better price since they sold me a defective 350..who knows?

Maybe that 350 2bbl could get "lost" in return shipment!.....he he
I have a buddy that runs a 3904v Holley on his 302, during warmer weather he gets 21-22 mpg consistently on the freeway, sometimes better........and when the secondaries open, its a kick!.........Of course, its in a Bronco II!

lol I suppose it would kick! This Edelbrock I have on mine now I yanked off of a friends blown up chebbie that was sitting in the trees for the last 5+ years...it runs OK but I'm very sure that burns way more fuel than it should, and I'm not too sure that the secondaries are opening. If they are, I sure can't tell anyway, but that could be the 3.00:1 gears in the axle on that one...oh well, I have to rebuild the axles anyway so maybe while I'm doing all that, I'll keep my eye out for a cheap 390 and try it just for kicks and giggles....who knows? maybe this one will work?

I bought it as an FDO from Advance Auto Parts, it was about 300 something, but I used to work there and know most of the guys behind the counter yet, so they knocked it down to 280...I was really happy with that, but its only a piece of junk now....
