Re: Holley carb id (78 corvette)
Holley tracks their carbs through the list number stamped into the front surface of the choke airhorn. It should say "LIST XXXX" . 7445 and 5263 are not valid list numbers. 9895 is, in fact, a Holley list number. A 9895 is a Holley model 4175 carb, 650 cfm vacuum secondary, using part number 122-592 primary jets (close tolerance), 134-21 secondary metering plate, 125-206 power valve, .037 discharge nozzle, and a black secondary vac spring.
