Procomp Holley type carbs

I just did a customers 950 billet main body. They need a little help in the metering block, other wise it ok from a rebuid/ test run standpoint. I will say that that particular carb was 3 circuit, and the way they made it 3 circuit was pretty slick. It was all done in the main body using a 2 circuit block. Again, I did not race this carb only test ran on my mule engine.
