I may or may not be a better choice. An I6 conversion to a V8 may be desirable because the chassis hasn't seem power from a V8 ever. If you find a rust free I6 it may be a much better investment time wise to convert it to a V8 then it would be to sink money into body work on a V8. There is no clear cut and dry answer. Not to mention that someone have have owned the I6 for a long time and become attached to it. Definitely a good question but its one that each person should ask themselves and answer themselves as well.
