Fan Issue Blue Print 360
Like stated before, it’s the late style pump/radiator and I’ll bet the aluminum radiator is pretty thick. You are so invested in the late style, you should stay with it. However, to get that motor to work in the older style car you just change to the cast iron pump. (Still in stock at parts stores). You can see the timing marks under the inlet if you move your head around or just make a pointer for the passenger side. Then install timing tape in the correct place. The problem is the inlets changed sides and everything you have now is for passenger side inlet?
