That only works if you use a 6" diameter damper. Look up one for a 265, 283, or 307 V8. I use a Ford 302 V8 water pump pulley and modify the shaft hole and bolt spacing when I want a 2-groove pulley on the old 216 style high water pump. The original cast iron pulley has to be machined down so the Ford pulley will fit. Having two belt grooves on the damper and the water pump gives you all sorts of mounting options for accessories like power steering and/or air conditioning.
