Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_23166 ( "RPM" real, "Standard HP" text, "Standard torque (lb/ft)" text, "Standard speed (6th gear)" text, "Modified speed (6th gear)" real, "Modified HP" text, "Modified torque (lb/ft)" text )

### Question ###
What is the modified speed (6th gear) when standard torque (lb/ft) is 10.3 and modified torque (lb/ft) is 8.75?

### Accurate SQL ###

SELECT "Modified speed (6th gear)" FROM table_23166 WHERE "Standard torque (lb/ft)" = '10.3' AND "Modified torque (lb/ft)" = '8.75'
