Would anyone know the application of this water pump? What the numbers stand for? http://www.yenko.net/ubbthreads/images/graemlins/confused.gif

It's probably 3992077,which was orginally installed on 1971-72 Corvettes with 454/365HP or 425HP,and 454/270HP respectively.
Yours shows an October 27th,1971 casting date,so the later 1972 Corvette would apply.
