Does anyone know what the gear ratio is in a 1974...ish Rotary Mazda truck ? I am wondering if the ratio will allow my '85 SE to rev up faster. I don't really care about good gas milage on the freeway. I do most of my driving on the city streets, (actually, there isnt more than 3 miles of freeway here where I live). So, anyway...a little info on the ratio and installation possibilities will be greatfully appreciated. THANKS.
