I have 75 Pace car, on the hi-way lots of power, off the line, slow. Looking for 373 posi rear end. Any one have one? how much? Or do I need a differant ratio. I want a good start,like a good tire burn, but on the Hi-way I don't want the engine to be screaming at high rpms. Is the 373 ok, or is there somethig better. Thanks
