Re: Four barrel
Ran a Holley 390 for a while and it ran well right out of the box but when I decided to set it up with fuel efficiency in mind using an A/F meter I found it to be overly rich on the idle circuit and could not get it to idle slow enough ( auto tranny ) . Was told and also read that Holley uses the secondary circuit as part of the idle circuit in an effort to prevent fuel stagnation in the secondary bowl due to lack of use. I have since changed over to a used Edelbrock 1404 which I rebuilt and what a difference in tunability. Needless to say the 390 is now bringing enjoyment to someone else.
