318 to 390 stroker

We got the rotating assembly back finally. Ended up right at 10:1 compression. DCR calculates out to 7.9:1 with the comp xe274 cam that the builder recommended. Should be quite the runner all said and done. We have a tc coming from ultimate converter with a stall in the 2800 to 3200 range. Do any of you have experience running a holley avenger carb? Thinking well slap on a 670 avenger.
