Carb recommendations for my 340

Hey everyone,

Looking for a carb recommendation for my 340. Car is a 71 Dart swinger with a 727 that has a shift kit and an old hurst autostick 1. Engine is 10:1 with a 484 purple cam, ported x heads, TTI headers and can’t exactly decide on intake. Currently has an LD340 mounted right now but plenum divider is removed from previous owner and not sure how well the car will be in terms of street manners as it’ll be a street car with occasional trips to the track a few times a year. Worst case I have an air gap on the side. What would you guys recommend? I’m new to carbs so would like to find something that’s good but simple enough for me to learn to tune.
Intake is an excellent piece.

770 Holly Street Avenger with vacuum secondary's for street use with an electric choke.

Holley 0-80770 770 CFM Street Avenger Carburetor

Works fabulous on my 408 stroker.
