Greg,
The best way to tell how it influences the way the car goes is to talk to someone who has changed the diff to a 3.7 to 1 ratio. If you are attending the next club meeting come and see me and I will introduce you to 2 members(one of them has a 6 speed and other one has a 5 speed)that just have done the conversion. I have the orange harrison so it should be easy to track me down.
