Which pulley size is correct?
Want to put finishing touches on rebuilt 350. Summit billet alum pulleys are 6.6" for both crank and pump. My stock sizes are 6.625" for crank and 6" for pump. Chrome steel pulleys are not the same either as my stock or the billet. Confused!!!! Won't a diameter change to any pulleys size affect the water pump and the alternator turns?? :confused:
