I need help identifying this Quadrajet. It belongs to a friend and he wants to sell it. I know nothing about them, so I am calling on the pro's here. This is a reman carb, and the small round plate with the model number is missing. We need to find out the application and fair price for it. Thanks for any help you can provide.

 

The fuel-damped dashpot on the secondary air valves would indicate that it's a 66. Yes, Olds used the side-inlet for the 1966 model year. Without the tag it's difficult to be more specific from the photos alone.

 

Randy, it looks to be a 66 model. 66-67's had the side fuel inlets
like this one. 66's had the toilet bowl flush (arm across the secondaries.)
As far as worth? No idea.
