Default Ford 392W with 3:11 rear, TKO500/600 ?

I am putting a Ford Motor Sports 392W Crate motor into a Backdraft racing Cobra. It has a 3:11 rear. The engine has 430HP and 450 Torgue. Which TKO should I use a 500 or 600. My concern is not just the torque but the gearing. The 500 and 600 have different 1st gears and the 600 offers 2 different 5th gears.

Thanks

Cobrak
