Ok after looking further, the 9.5 has a 2.5L engine in it, butit is dual overhead cam and our s is single overhead. The 2008 also may include cam fazers which yours may not have and your computer would not be able to handle teh dual fazers as it's not set up to operate them. Why not just rebuild yours. Even if teh block has a hole in one of the cylinders you can sleeve the cylinder and it's like a new engine. Either that or see if GM parts direct carries that engine an dyou can get that. It would be the same motor with no dress items, alternator, etc. PLus it's brand new.
