I have a chance at getting a 3.4 motor out of a Oldsmobile Silhoutte mini van, not sure how you spell it, my brother might be buying it for scrape parts for his mini van, he asked me if I would like to have the motor if it would work, my Cavalier has a 3.1 motor in it, now, he was curious as to if this transition is possible at all, for my Cavalier? Would there be any modifications that id need to make for it work? Thanks, I rather would replace the motor if i had the chance to get a good deal on a motor rather than pull everything out of the 3.1 and try to fix it. Thanks again guys!
