6.5 inch crank pulley and 6 13/16 water pump pulley. Both from 440 source.
Ok. Feeling kinda dumb. When I look at the radiator it is a cross flow radiator which puts the tanks at the sides. The core is 22x18 even though it is listed as a 26x18. The width of the core is correct for the opening but where I have it mounted the top 3-4 inches is blocked off and the bottom of the fan sits below the bottom edge of the core by a couple inches. Why did I mount it there? I don't know. I will need to get a new radiator as well as new pulleys. Any suggestions on models of radiators. And shroud? I am looking at crank pulleys for AC at 7 inches and water pump pulleys at 5 7/8 inches
