I ordered a set of black aluminum ASP pullies today. What size belt do I use, will the stock belt work? Curious beacuse I also had ASP pullies on my last Mustang a 91 LX 5.0 and the stock pullie still worked.
stock serpentine belt is fine. my advice is to go buy a new one while you are at it. i have the habit of always buying new stuff whenever im modding. some would say its a curse, i just say insurance.
