My 1998 Bonnie SE needs a new engine. I found a 58K mile 3.8 from a 2003 Regal. What do I need to know about dropping the new engine into my Bonnie? Will it be a straight drop in, or do I have some serious mods to do?

You will have to change a few bits and pieces... all the parts on the 98 will swap to the 03 motor... Unless you can alter the tune you will want to use the 98 Throttle body as well..
