I'm trying to find out what a Holley LIST4698 carburetor is and, in
particular, what vehicle/engine it might have been original equipment for.
Holley doesn't publish any info for it, and a web search yielded zilch.
It is a 4150 series carburetor (i.e., it has metering blocks front & rear),
and it has vacuum-controlled secondaries.  It has center-pivot
(cathedral-type) fuel bowls and automatic choke.  By uncalibrated eyeball,
it appears to be about a 600 cfm unit.
Thanks!
