holley carb identification

[LazerStang760]

I need some help finding out exactly what kind of carb I have on my car. It was already on when I bought it. It's a holley carb and the only identifying numbers I see without taking the carb off are: List 1850-3-1891 up by the choke, 3,572,387 3,343,820 2,392,622 just above the Holley in the front. I've looked on holley.com and searched google couldn't find anything.

600 cfm vacuum secondary.

Thank you D.Hearne, how did you look it up? I'm trying to find a choke for this carb.

All the 1850's are 600's. Includes the dash one's thru 3's. Any choke from any Holley model 2300, 4150 and 4160 will fit it. The 2300 is a 2 bbl , the other two are 4 bbl models. Most of the parts are interchangable between all. 1850 is the list number that identifies it as a 600 cfm 4 bbl.
