Best Gears for a 408 Stroker?

Well I'm late to this party but in the interest of more info, here's the gear/speed/trans calculator I use. I like it a lot, as it's easy to change things up and see what that gets you. It comes preset with lots of stuff but you can manually enter any value you want and it still works.

Speed/Tire/RPM calculator

Too bad you already ordered 3.23 gears, I have a 489 case with 2.94 gears sitting in the shop. :(
