I have a Holley Carb and the only number I see on it is R84021-1/2985....

 

im not a holley guy but as far as i know its usually on the choke tower as you look at the carb from the front, youll see a number like 3310 on the upper left or right side i cant remember which but i think its right

 

It's on the choke tower. It'll say LIST 0-1850-3 or something like that.

 

what if the carb has no choke / had choke but it was removed ??

 

The choke tower is typically cast into the main body of the carburetor. A notable exception are the Dominator carbs made after 1983, as they come without this choke tower.

But anyway, back to the issue at hand.

On one side of the carb, you may see a fuel line running from float bowl to float bowl. This typically indicates a Holley carb with vacuum secondaries.

www.mortec.com has listings of list numbers for Holley carbs, and also, the Haynes manual for Holley carbs has many of the list numbers, plus all info needed to rebuild any Holley carb back to factory specs.

 

ok so...
