I have heard that there is a waterpump housing from the factory that has the oil cooler, and both heater hoses blocked off already. I saw one on ebay that looked factory made and it was advertised as a factory drag pump? Anyone know a p/n if this is true? I would really like to have one

 

I never heard of one that has heater hoses blocked off, but the Corvette LT1 pump doesn't have the 'bypass' hose provision..[oil cooler]
I can get the p/n off it if you need that [it's in the garage]
It is different than the Fbody LT1 pump
