[QUOTE=Dixie Design;5734]Summit's kit for the 4.6L 04 New body style and up replaces the same, crank & waterpump. The Crank was definitely bigger than stock. Their kit for the 04 Heritage and older was a 3 pulley set, with a new alternator pulley being the 3rd.
Are You sure the crank pulley was larger???? That would be an overdrive.
