Because of this change the hole in the block has been deleted. Which has led to some water pumps being remanufactured using housing not containing the passages for the gen 1 SBC bypass.

I have a CT350 GM crate engine (CT = Circle Track) which came with Vortec heads. It just has a regular thermostat in it and a GM Performance dual plane intake manifold (which it came with). I have not had the engine running yet, but sounds like I need a different thermostat. Heater hoses were not connected when I got the truck project, so I need to figure out where they are supposed to go.
