The motor isn't the limiting factor, the blower is. A blown motor will only make what power the blower pumps through it. The smaller the blower on a larger cubic inch motor, the faster the overdrive has to be to pump more air.
Pumping more air, less efficiently means more heat in the intake charge because the rotors are beating the snot out of the air. The more the air is heated, the less that gets into the cylinder...
It all comes down to the blower. If you left the carbs and blower alone, and increased the motor under it, chances are it's not going to be any faster than before.
It would be a LOT faster if you put 2 alky carbs on it, simply due to changing the air intake temperature.
