The Holley Ultra Street Avenger is a decent carb.
I had one on the 505" stroker before going to port EFI.
I wanted a street carb with electric choke and vacuum secondary.
As I recall, it had billet metering blocks, but pressed in restrictions, not screw in restrictions like most billet metering blocks.
The idle restrictors were a bit small for my application, but other than that, it was a good carb.

If you don't need a choke and looking for more of a race carb, the HP carbs are nice. I have an old 1,000 cfm vacuum secondary HP carb (no longer listed by Holley) that was really close out of the box for the old 451 stroker combination, and worked good on the 500" stroker too.
