Tuff question!
Maybe break it down into effects on the converter.
Less vehicle weigh = less load on the converter and that would bring down the rpm the converter flashes to.
Depending on the motors current power band this could be good or bad I would have to guess.
Reinstalling the bigger carb equals more torque and Hp.
I think you have found what effects this brings to the table if I recall right?
The gear change will load the converter harder and in turn using up more or all its stall speed.
All and all I don’t see you getting all of the mph increase your looking for, especially since no added rotating component resistance ( tires ) , Nor added wind resistance factor has been added as needed into to the equation.
My proven trusty Moroso slide calculator is telling me that to hit 146 mph you need 700 Hp and a 2900 lb car regardless of gearing.
