I'm running Bill's Stage II valve body and Dominator torque converter making a good bit north of 600 rwhp on a otherwise stock NAG1 and loving the valve body and torque converter. No issues, but soon will be getting the full built transmission!
I assure you the habit of modding only gets worse! I know how people on drugs feel. I'm afraid I will start pawning sh*t if I don't get control of myself!
