aspen station wagon upgrades

Hello, i have a heavy aspen station wagon with super six ,automatic,and 2.71 gears. i've done a tune up, lightweight starter,and upgraded exhaust to 2 1/4 pipe and turbo muffler. i bought a used offenhauser 4 barrel intake ,and i have a n.o.s. carter performer 500cfm electric choke. my question is ,will the carb be too radical on stock engine? if not,i'd like to procede with that,and then maybe 3.21 gears.
