My parents have a 94 Buick Regal. It presently has a 3100 engine in it, which is blown. They were considering putting a another engine in it. I have found several 3.1L engines. Since a 3100cc and 3.1L are the same size? Are there any significant differences in these engines that would make it difficult to place the 3.1L into a vehicle which had a 3100 engine in it?

Thanks for any information on this.
