Hey i have a blown head gasket on my grand prix it is a 1999 grand prix se with the 3.1. Now i am wondering if it would be possibly to switch it out for a 3.8L. Does anyone know if that is possibly, and if so, how much work is required to do that?
 


Sure its possible and a few have done it.

You'll need the engine, wire harness, pcm and a few other odds and ends. I am not sure if there is a write up on the exact list.
