Pard that is a 30 year old factory low compression motor and the 84`s do not run as good as the 88-89 I promise. Reason the 88-89 run better, they were cheater motors for when Bass had a 150hp limit. Test have shown them to put out 175 to 185 hp. I still have the 89 GT 150 if you find out you need a motor.
