Thanks for all the replies.This info will help me in deciding which gears to go with.I might go with 3.55 but i will think about it.Thanks again for the help.

I need to get the readend fix in my dart but i am not sure wether to go with 391 gears or lower.It will mainly be driven on the highway,maybe on an rare occasion,a run down the dragstrip.Thanks for any replies.
