Thread: How to ID your Engine?

Hi all. I know the drill and searched the forums first, but could not find something specific to my question.

How do I ID the engine in my 99 Grand Prix?

It was a salvaged car. The plastic cover for the motor that ID's the motor is gone. Nothing on the inside of the door or under the hood that I can see. This is not a super charged model. At least not that I could tell.

Advice?

Thanks!
