Those engines are significantly different. Just the intake setup and the ignition system are different enough to make this a tough swap. The engine internals are also different, as the heads use a different lifter setup. Whether the trans is the same depends on whether the two cars have the same vin designator for the engine. If both engines are either Y or 9, then the transmissions can swap, but if you put the transmission from a 9 engine into a car that has a Y engine, you'll create problems that you'll never overcome, as they are geared differently and have different torque converter clutch systems.

An engine from any 96 to 99 Deville, Seville, or Eldorado will fit into your car. 98-99 Seville used a different mounting setup, but the engine will still work. Don't use anything newer than 99, though, they are substantially different.

Jerry

thanks for the reply although that is not what I would like to have heard it is what it is.I was told it would work by another person but knowing him for some time I thought I needed to look for further information before I opened a can of worms.

Thank you

Ross
