Truthfully the fuel economy should improve if you use the overdrive. I know my uncle had a truck that was set up for overdrive and he put a 4 speed tranny in and the fue economyl was horrible. Either way let me know how it turns out, I was thinkin wether or not to put a 5 speed in mine.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
