It is bolted to a th400 and a 3:73 rear. Today I took it for a test and the water pump snapped at the bearing and the fan went out to lunch with the radiator for it's main course. I was using a 7 blade fan and a fan clutch. I think the weight of the fan and clutch was just too much for the quick torque. With this kind of power, would it be best to use a fan with the alum. blades that will twist under power and do without the fan clutch? I really didn't care for the noise it made when parts started flying. Anyone have any thoughts?
