I had some Ansen ball bearing progressive mechanical linkage on my wife’s 440 six pack car.
it was flawless as long as you didn’t kick it from a idle. As long as you brought the rpms up a little over a 1,000-1100 rpms zero hesitation. So a 4 speed car would be a moot issue.
The Mopar six packs flowed 1350cfm and the center carb was 350cfm not 500.
The outboard carbs were 500cfm
An 850 double pumper is a great carb with a 4 speed car, and a 440

I have another set of draglites with some 275/60 drag radials and some Goodyear’s on the front.
Yours looks great as is! Not sure I would change a thing.
