The 351 Cleveland engine, if I recall, was rarer, and more coveted, high performance engine.

The 351 Windsor was the workaday one, found in trucks too, and Police cars as the "Interceptor" engine.

I am pretty sure the "Windsor" engine was made in the STAP in Windsor, Ontario Canada, and you can guess yourself where the Cleveland engine was made.

1991 was the last year the 351 went in any of the passenger cars, (Ford Crown Victoria, Mercury Grand Marquis and 1990 for the
Town car), and in those last years they had carb trouble.

By 1992 they were all running the new, highly touted by Ford, modular 4.6 engine with EFI, which they still do today.

A tough, durable, long lasting engine, that will never win prizes for fuel economy or efficiency.

Probably the best one to have would be one in a 1969-1970 Mustang "Boss 351", with few smog controls, a screamin' tire smoking, REAL muscle car with a real V8 american rumble at idle
