regear calc/spread
allright guys I just wasted an hour of my life searching for a excell spread I saw a while ago for the f150 where it showed your speed at given rpms and all you had to do was enter in the dif gear and tire diameter. I'm looking to change my 3.73 out for more accelleration. it makes no sense to top out @ 100 in third gear @ 3000 ish rpms I'd like to use the full potential of the tranny and powerband
