OK so I'm to a point where I am getting ready to drive the 71 grande and I've got a cooling issue. It looks as though the heater core has been bypassed, but I need to know if this is right. It over heats within 5-10 minutes of running. Does this hose arrangement look right for bypassing the heater core?

That is how mine is hooked up. Works fine. Maybe your thermostat is stuck.

Well I removed the thermostat and now she runs a cool 130. Normally it would have been my first thought, but I was told it was new. Thanks for the help once again.

This is a to be a drivable project and I think I'm about there.
