third gen Camaro rear swaybar question

i’ve got a 91 camaro V8 5 spd. i’m doing a rear end swap now, and since i have the sway bar off in the back (and the bushings all look alittle worn) i was concidering an upgrade from the stock 3/4" (approx guess) to a full 1" sway bar, its not a racecar by any means, but i do have a heavy foot on the road, is this worth putting the money into the 1" bar? or will the improvements (or potential negatives) be not worth it? thanks for any suggestions, i dont know much about suspensions.
