Wondering if anyone knows where I can get a crankshaft that is equivalent to the one used on the 93 Cobra and 93 Cobra R. This is the info. I have read in a forum: The water pump and crankshaft pulleys were a different diameter than the regular 5.0L. The crankshaft pulley was reduced in size by 14% to underdrive the other accessories for more power but the drawback was a slower spinning water pump. To solve this problem, Ford also reduced the size of the water pump pulley by 14% to bring back the lost coolant flow. Part number for the crankshaft pulley is F3ZZ-6A312-A, water pump pulley is part number F3ZZ-8509-A and part number for the now shorter belt is F3ZZ-8620-A. So, just wanting some help so that I can used the shorter belt. For the record, Ford discontinued the crankshaft pulley part no. F3ZZ-6A312-A.
