I came across a newly rebuilt 440 that was placed in a car for 12 years and barely driven - less than 100 miles. They lost interest in the project and passed it along to me. Problem is they installed an aluminum radiator in it with the wrong type of coolant so it looks like some electrolysis has been going on for the last 12 years. I'm dissembling and inspecting the motor and have found the treads on the iron water pump housing are pretty brittle and corroded so I'm replacing the housing. I also found the steel freeze plugs have been literally eaten through. The water jackets on the block and heads appear perfectly clean with no signs of corrosion. Can anyone tell me in there are certain spots within the block and heads that would be most affected by this? I don't want to overlook anything when reassembling the motor. Thanks
