When I was much younger, my father had two Ford Falcons and 3 FF motors. He would piddle around on the third motor, cleaning cylinders, grinding valves, or some such thing. Then, every 50,000 miles he would pull a motor and put in the extra. He got 350,000 miles on one of the Falcons, but the bottom finally rusted out from snow and salt. I wonder how he would have done in Florida?
Funny in a singularity sort of way. My first car was a Ford Falcon. Strait six and very easy to work on. Replaced the generator brushes every 1500 miles. Did I mention the rust problem?
