Being an '88 it came with a 2.8L V6. It still runs ok, on 5 cylinders. But hey, it does have 250,000 miles. Will the stock motor mounts work for the 3.8?
I know the '88-96 Buick Regal is on the same platform/bodystyle as the Grand Prix. The Regal came with a 3.8 from the factory, so why can't a 3.8 fit in the GP?
There are alot of old 88's and LaSabre's out in the salvage yards so I don't think it would be hard to find one if I can make it work. What do you think?
