So for my car would the 750 with annular boosters be overkill?

I know it really likeed that 750 Mighty Demon mid range and top end it pulled much harder, the bottom end was no better or worse then the 650. Both the engine shop and Quick Fuel are recomending I go no bigger then the 650 however.

So it seems as the choices sit at 650 SS Double pumper no annular boosters or step up to the 750 with the annular boosters



The 750 with annulars just plain works better than any other carb I have ever had.
