You are correct about 4.10 rear end. The '93 has a 4.10. Same effects that I noted. It just happens at different speed/gear combination.
As far as using a pressure cleaner hose to blow crap out of the radiator, be very careful. The fins in these radiators are very thin aluminum and it would be easy to bend them over with a pressure washer.
Thanks for the warning about reducing the bypass flow and causing over pressure in the radiator. I plan to proceed carefully. The over pressure problem will only occur at high water pump flow (engine rpm at 7000). At that water pump pressure, the coolant bypass will be opened against its spring pressure.
What I am trying to reduce is the bypass flow that occurs all the time (even at low pump pressure) because of the notches in the bypass valve disc.
I would like to find a ZR-1 that doesn't do what I described and find out what brand thermostat it has.
