Will a ford engine fit Oldsmobile car?

It depends on the year and model of both the Ford engine and the Oldsmobile car. Generally speaking, it's not a straightforward swap. While it *might* be physically possible to fit a Ford engine into an Oldsmobile, it would require significant modifications and custom fabrication. This is because:

* Mounting points: Ford and Oldsmobile engines have different mounting patterns. You'd need to fabricate new motor mounts.

* Transmission: The transmission bellhousing will likely be incompatible. You'll need to adapt the transmission or use a different one altogether.

* Wiring harness: The electrical systems are different. You'll need a custom wiring harness.

* Exhaust system: The exhaust system will need to be custom-made.

* Cooling system: The cooling system may require modifications.

In short, while not impossible, swapping a Ford engine into an Oldsmobile is a major undertaking requiring significant mechanical expertise, fabrication skills, and a considerable amount of time and money. It's far more complex than a simple bolt-in swap.
