I'm not at home to measure it, but it is the stock multi-v type pulley, I think it is about 3.5". I have considered changing the crank pulley to about a 4.5", which would slow down the water pump and the 2 alternators, but haven't done that. If I don't do that, I figure I need to change the alternator pulleys which are 2". Have you noticed the size of the crank pulley on the 26B race engine? It is about the same size as the alternator pulley.
