pic is not so great here is the exploded view
this is a 465 I think, holley number 1848-1.
Barely got the butterflies out, both shafts are seized, I think they will have to be cut out.
Most of the aluminum is ok, But almost another entire carb will be needed to rebuild.
see next pic of bowls also.

 

Here is a pic showing the difference in bowls, the bowl with the white float is the accel pump bowl
Is this for all holley's, or rb's mod?
The side w/o the accel pump had no jets, some sort of block off plate, and a metal gasket, Is this rb's mod as well?
The side with the accel pump had #49 jets
As you can tell I know nothing about carbs.
Someone make me an offer if they want this thing.

 

Wow, was that under water for 10 years? Not sure about the floats. The secondaries on a 4160 carb dont use regular jets. the plate you refer to is a metering plate which has fixed jets/holes drilled instead of jets. Thats standard Holley.

 

Will you take belly button lint for it? I'm broke.

 

sorry, sold. you going to rotary revo rutnick?
I can't remeber If I asked you or not.
If so follow me and rotofire up there.
