I don’t know it off hand, but I can get you a crank pulley to K frame measurement. You just need the front face of the pulley to the front edge of the pinch weld on the K?
It’s just a curiosity, I think it will be ok and either way I will make it work. Just another data point.
Yes, I measured from the face of the pulley to the front edge. Now that I think about it, yours will be different since you are running a wide belt and no power steering pulley.
