I don't see why not..

Yes. Impalas used the 3800 series engine for a while. You might have to get a different wiring harness but thats not too big of a deal since some of them originally came with that motor.

Physically, yes, it will fit. The 3.8 is the same across all GMs. But legally, no, it will not. To be legal in this country, the engine has to be the same year as the car it's going in, or newer. The car can't be newer than the engine.

Only if the Impala came with the 3800 engine. No, it will not work if the Impala only has the 3.4L engine. Doesn't quite work like that to upgrade engines in newer cars. Not an easy nor cheap task to do. Has to be the same size engine. also not sure I would use that old of an engine either. More than likely the sensors will be an issue too since they will have changed designs & the connectors will have changed shapes as well

your transmission in your Chevy won,t bolt up to the Pontiac engine because the bell housings are different ! but as far as the engine fitting in then yes it should sit right down in !
