I recently put a big block in my 73 SS Chevelle and the fan shroud that I had was for the small block and doesn't work. I have a long water pump and I was wondering if anyone has any idea of a stock fan shroud that will work with this application.

Check out "Original Parts Group".
When I replaced the 305 in our 76 Malibu Classic with GM's 454/425 crate motor http://www.chevelles.com/forum/smile.gif,I had a fan shroud problem until I ordered a big block shroud from OPG.
