What gears should i run?

Its in a 71 dart with a 360 magnum, basic bolt-ons (headers/RPM intake/750 3310) & a re-ground Bullet cam (.477 lift, 216/218 dur. @50, 112 LSA), 904 trans, Hughes 2500 stall, 8.3/4 rear, right now its a 1 legger with 2.76s & the 741 case, i would go with 4.10s, but the kicker is, in the near future i'll most likely throw a 100/125 shot at it, so i'm thinking 3.73s, any DR i use will be about 26" tall.

Depends on what you plan on doing with the car.
Strip only
Street/strip
Daily driver.
