Help IDing this Holley - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey gang.

I need some help figuring out what Holley I have here. I've gotten the all the numbers that are stamped on the thing and the closest I could find was a 580 that was sold on the 66-67 Corvettes. But when I got the rebuild kit for that carb, it turned out it wasn't for a matching carb. If any of you guys could point me in the right direction so I can finally get this thing tuned. If I slowly accelerate, it is fine, but it I get on it, it falls on its face. I'm not sure if I'm running lean or rich or whatever. Anyway, before I digress any further....

If any of you guys could tell me which adjustment screw is for the idle and which one is for the power circuit.
