I posted this question last week but it disappeared so i will try again....
My 65 mustang has an original 289. I live in Florida so I have no need for heat. I disconnected the heater hoses at the intake manifold and block. I put rubber caps on the water ports. A friend was over and told me that it was wrong to just cap the ports and that I should have put a small hose from the manifold heater hose port to the block heater hose port. He claims it will cause overheating the way It have it.
Does anyone know which is the correct way to delete the heaters hoses
Thanks

You will find, however, that opinions vary and some have deleted their bypass as well...I'd definitely keep it.

What is the purpose of the bypass hose

What is the purpose of the bypass hose around the thermostat on a 65 289? When I drive on cold mornings I have to put a piece of cardboard in front of the radiator to keep it warm. When I don't and I let it warm up enough for the thermostat to open, it will still cool down once I am on the...
