Unknown Holley Carb

[pleze1988]

Hey everyone. I just bought a Holley carb on eBay for cheap. The issue is I don't have a clue what the thing is. The seller says it's a 600 cfm manual choke, but the list number is strange (-62). Maybe one of the gurus can help a guy out and tell me for sure what it is I bought and if they see any missing or damaged parts (looks like something is missing on the throttle side) in the pictures. This will be going on a mild 305 (bare bones Lunati cam, dual-plane Weiand, ported heads & headers). I appreciate the help.

Looks like a spread-bore as well.

I'd say it's a 6291, since there are no other carbs starting with 62 that are 4160s. Having said that, I'd say the throttle body secondary size is larger, and the boosters are drop down, not straight like this one: https://www.ebay.ie/itm/HOLLEY-600-C...MAAOSw8o9duPuu. An unlucky find, since the stamp missed with all the details. Gary
