So i swapped out my engine for a 93 Mustang 5.0 H.O. with the whole serpentine pulley setup. I'm going carbureted until i can get the computer to put in the fuel injection installed. I'm having issues with the lower radiator hose. Can someone give me a part number that will fit with the stock radiator and the new engine, as the old radiator hose rubs against the serpentine belt? any suggestions???  

Are you using the stock Mustang radiator with the outlet on the passenger side? If so you'll need to fabricate a steel coolant tube, use a flex hose (either rubber or something like a Cool-Flex), or purchase the hose adapter kit from Ron Morris Performance...

HTH...
