Just as the title states. If you do, what kind of tune are you running and how are your results if you are willing to talk about this carburetor?

Was that an OEM Q-jet replacement or something?

It an old school 800 cfm Spreadbore double pumper with dual feed. Nowadays you can only get a 650 cfm spreadbore. They were designed for a Quadajet carburetor replacement.
