I have a factory Original 1970 Z28 Holley carb, numbers matching, what is it worth? The carb needs to be rebuilt, but it has all the parts.

Chevy Part Number: 3972121

Holley List #: 4555

Holley Build date #: 013

$300-$600 IMHO depending on condition, access parts etc. Repops are 599.00 or so on ebay. The 4555 is coded for a 4 speed, so if it's real and not a repop, it may be on the upper side of the price.
