Student, huh? I spent nine years telling my students, "what you heard is not what I said". I don't know if the new engine will run just fine with the old computer. I DO know people are switching from the 2.7L to the much better 3.5L on newer Chrysler products and the same computer can be used. Chrysler has always been famous for excellent parts interchangeability between years, models, and engines. That is the original reason I first became a fan of the company.
When I worked at the dealership though, we never got involved in things like this. You usually won't find a mechanic or a shop willing to change engine sizes either because emissions laws come into play. In this case, once the engine is running properly, the emissions will likely be the same as when it was in its original car, but it will not match what is on the sticker under the hood. That's where the over-eager, idiot politicians have their noses stuck, (up your tail pipe), and have made life miserable for us.
