Table schema:
CREATE TABLE table_19704392_1 (modified_speed__6th_gear_ VARCHAR, standard_torque__lb_ft_ VARCHAR, modified_torque__lb_ft_ VARCHAR)

Question: What is the modified speed (6th gear) when standard torque (lb/ft) is 10.3 and modified torque (lb/ft) is 8.75?
SQL: SELECT modified_speed__6th_gear_ FROM table_19704392_1 WHERE standard_torque__lb_ft_ = "10.3" AND modified_torque__lb_ft_ = "8.75"
