Classic over carburetion problem?

Comp .488/.491.......sounds like it’s a XE274.

The car would be livelier with a quality 10” converter in it, that flashes to around 3200rpm.

I don’t love VS carbs, so the next move for me, after the converter would be to use a 650DP carb.
I just prefer the feel of how the motor responds to the mechanical secondaries.
