Hey guys. Dumb question, but how much of a pain would it be to swap a 2000 model year N* engine into my '96 DeVille? Or am I just asking for trouble? I'm currently battling an overheating/possible head gasket issue, and I figured since the ol' girl has 163,000 miles, I might be better off to install a new engine. Any thoughts?

The 2000-up engines are very different and it would not work with your '96s computer.
So to swap, try a '99 and earlier.

Thanks very much for the help! I appreciate it. So as long as is 94-99 Y-code, it should all interchange and work with my computer, right?

Well, the 93 and 94 engines had a different intake manifold, so if you use the one off your 96 they should work fine.
Are you sure your Deville is the Y code? I thought it was the Deville Concours that had the Y code L37 engine. If yours is the Deville, it should be the 9 code LD8 engine.

Stick with a 95-99. You cannot just put your intake manifold on a 93/94. It will not bolt up and the EGR system will not work. The 2000 and later engines are quit different with different crank sensing schemes and sensors and the individual coil at plug ignition to name two major items. The 2000 and later PCM is TOTALLY different from the 93-99 cars and you would be looking at rewiring the entire car to begin to stat trying to put the 2000 engine in an earlier car.

I would repair the engine you have. It is likely fine if the head gaskets are replaced....

Pretty sure. The eighth digit is a Y for sure, can't mistake it for a 9 very easily. And no, my DeVille isn't a Concours. So what's that mean? Do I have a special order car or what? What kind of motor did the Eldos and the STS's run? Are they 9 or Y?

I think in 1996 they made the LD8 the base engien in the Deville, and the Concours got the L37. I know that my friend 1995 Deville concours has the LD8 engine, so i think the change was in 1996 along with the switch to OBDII. Bbob, you would know better than I would probably, but I think the 1996 base Deville would have the LD8 (Y) engine.
