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!
