Pulley ??

There are a few bb water pump pulleys under 6 3/4 inches down to 6 1/4 inches. Also crank pulleys of different sizes. They are getting dam hard to find. The depth of the w/p pulley needs to be approximately 2.75 inches deep. A small block pulley will bolt on but then u have other issues. As stated b4 the bb were almost always under driven. Kim
