Ah....ok. Well, that pump is either a Vortec 5.7 or 4.3 and either way, you'll be better off running a water pump from an 87-92 F-body. Then, you can use a stock type serp. pulley from that same car and be okay. Actually, if you haven't got them all yet-get a complete pulley set from an fbody-itll all bolt on....I do these serp. swaps all the type along with cooling fan upgrades to HO fan assemblies.
