Tires / diff ratio advise

I am working on my 69 dart that will have a 440 /727 / 8 3/4 in it . 10-1 cr, alum heads , The stall is 2800 and the cam builds at roughly 3000 to 6000 rpms. I can look up the Isky specs if needed. My question for advise is should I go 355 ratio and 15" tires ( taller 27/28" dia ) , or 323 ratio and 14" tires ( not as tall. 25" dia). I need a ring and pinion either way and rear tires and rims too. It's a project
Thanks for the advise !
I should include that it's a street car / fun car. Not a daily or a drag car .
