He claims it was bought new with the v8 in it so is it possible that buick made two options for engines that year in that model, one that was a v6 160 hp and one that was a v8 285 hp? all imput would be apreciate. thanx
All, repeat all '98 Buick Centuries left the factory with a 3.1 liter V6 installed. I don't know the hp rating off the top of my head but 160-200 is a good guess.
Is it possible to install a V8 into a car originally equipped with a V6? Of course it is. I think the question you mean to ask is, can you put a Northstar into a '98 Century. The answer to that is, anything is possible but to accomplish that would take a tremendous amount of fabrication. I doubt anyone has done it.
Finally, please have your friend produce some type of documentation (preferably online) to back up his statement. Better yet, why not just open his hood and take a picture.
