OK I looked at my engine & it does NOT have a bypass hose on it. Also in the CPP catalog the photos of the 350 Ramjet do not show a hose.
I wonder if the '96-'99 5.7 Vortec engines have this hose?
It's interesting to note on all my race engines I have always tapped & plugged that hole in the block but I didn't run thermostats, only restrictor discs.
But I can see why with the hole missing in the Vortec head it in theory should need the bypass to keep the pump from cavitating before the thermostat opens.
PS- I wonder if the hole can be drilled into the deck of the Vortec heads?
