Re: Block manifold and water pump after heater delete?

There is no water pump bypass on a vortec motor or motor with vortec heads or a lot of after market heads either. There is a place on the block for the bypass but it doesn't go any where , it dead ends.
Even with the water pump bypass it is still a good idea to run a bypass hose to help water flow through the heads.
