Do a search for 3.6L pentastar gear ratio chart. Very useful.

If you're asking a question like that you shouldn't be thinking about 37's, 38's or 40's

Really?

YES. How bad it is will depend on various factors. Which engine. Which transmission. Current gears. Any performance mods. Location. Use. Personal opinion. etc. etc. etc.

There are several thousand gearing/performance threads to read through for more information and opinions. Probably a good place to start...
