Carburetor identification HOLLEY

[THE ZUKE]

Hi guys, 
I want to know which model is my carburetor HOLLEY 4 barrels.
I can not find a big reference (ex: 4150 or 4160, etc).
I noted these references: 80870-1, 5533, 2053, 11697, 11981.
Could someone help me in my search?
Thank you for your answers

4160 or 4150 ?

Vacuum secondary is always 4160 as I posted above
870 = 870 CFM
Decent carb
