I have a th350 trans for my car and i am in the process of buiding a monster motor for it and i want to know how can i change my shift points to 6500 rpms and also what were the weights of the weights used and the springs?

 

A DIY way of modifying the governor is trial and error but it is explained in the TH350 handbook available at most performance shops. A better way of doing it is to buy the B&M Shift Point Kit.
