i was wondering if u could help us. we have a 1979 Mustang with a 1969 Boss 302 motor in it. the motor has a offenhauser tunnel ram with dual holley 600 cfm carburetors. we have some questions and didn't know if u could answer them. we got the thing to idle at about 1000 rpms where we wanted it to. then it started to bog down every time the electric fans turned on. it quit doing that but now once we get it to idle where we want it and it stays there when it is warm the next day when ever we warm the motor up it won't idle the same it always dies. we didn't know if u had any idea wat could be causing all this to happen.
