I have a set of pulleys that do not appear to be originally for a 400 430 455 by the part numbers. They do fit as I ran them on a recent 455. Does anyone know what the original application is? 1359065 is 6.75" diameter, one groove water pump 1365028 is 5.75" diameter, two groove crank Cheers!
Thanks, it appears both are from small block buick...various years. They fit 455 so diameter is what matters to match to the correct five or six fin water pump... :TU:
