Can you guys help me identify the model of Holley Carb on my car?
Please excuse the mess of the car. It's a 68 Firebird. It was sitting outside for the past 10 years.
As you can see, the carb is leaking at a few points. I would like to install a rebuild kit or at least some new gaskets so I need to know what family of Holley carb this is.
From what I have found online it looks like it's from the 4160 family? But, it doesn't have vacuum secondaries. Any insight would be greatly appreciated.
I am a child of fuel injection and really don't know much about carbs so thanks in advance. I really only want to get it fixed so I can drive the car around a bit before I tear it apart for the pro-touring conversion. A fuel puddle on the intake manifold just doesn't seem safe to me.
On a side note, I got the car started for the first time in 7 years yesterday! Ran pretty well actually.

Holley uses the List Number for ID. It is on the front of the choke tower. Looks like you can just about make it out in the pictures.

Looks like a 650 Q-jet replacement.
Sort of a PIA carb, but they run decent if dialed in.

The spread bores are great for a street car because of the very small primaries and extra larger secondaries. I still think the holley 750 is the easiest to tune and mod though.
