Big Block pulleys
How do you get the right size pulleys? What is the magical math formula? What is the stock ratio?
I was looking at purchasing after market serpentine pulleys but not sure how to figure what I need. I don't want to my water pump or charging system to suffer.
I was looking at: Crank 6.0, water pump 5 3/4 or 4 7/8, alternator 2 1/2.
Will this work?
