If going from a SB to a BB fan shroud will not work. However all 454 fan shrouds are the same from 1973 all the way up to 1991 so finding one should be easy. There is one in my shop, but it is not for sale. :)

GM just discontinued that P/N around the 2008 bankruptcy otherwise I'd send you to the dealer.
