I need some advice on what to look at next. I have a RamJet 350 with the vortec heads. It will not pump water through the engine. I replaced the water pump, thermostat, disconnected the heater hoses, drilled a hole in the thermostat, checked hoses, had my radiator checked by a shop, MK VIII fan works. The engine is new...only a few miles on it driving around the house. I dont know how long it has been doing this as my gauge did not work at first and I didnt fix it right away. :screwup:

I read some where that the Vortec heads arent drilled for a bypass? What does that mean? Could that be my problem? Any other ideas?
