I have been dealing with some cooling and charging problems on my 94 for some time now. I am currently using some underdrive pulleys. I am thinkin about going back to stock. Question.. Should I go back to stock (gt) or try to use the cobra waterpump pulley? From what I understand is its smaller yet then gt which will allow it to run faster. I assume I would need to go the 94-95 cobra belt also if I go this route. Any opinions on this?
