Where can I get a good engine to put in my car 2000 pontiac bonneville ssei and what'* the newest year engine I can put in it....can I put a 2005 engine in there..??

I am not aware of the extensive list of specifics, but any Series 2 SC should be a direct swap, and Series 3 SC can also be swapped too, but you would need to move over your super charger and other parts as well. The blocks should be the same, with some Series 3 engines having better internals. Hopefully this should help you expand your search some.

2005 is the latest year you can use for Series 2

I have a 3.8L SC engine running fine from a 2001 SSEi with 105k miles on it. Let me know if you would be interested in it.

Thanks. I am very interested...how much..?? And how can I get it and can u put it in or...??
