Yesterday at the car show when I was talking to an owner of a 71 mustang, we were discussing rear ends and he asked what set up I have which I had no clue. Well talking about it more, a few agreed I probably have 4:11 in Gertrude. Especially since the PO built her for a drag car. Everyone who looks at the engine, etc keeps telling me this car was built to run. :shrug
I do recall when I had a tach installed, she'd run over 3000 RPM on the highway. I think it was about 3200-3500 going I'd guess between 60-70mph. No speedo so based speed on the fact I'd be keeping with flow of traffic and posted speed limit ranged from 65-70. Oh and had this awful whine like it was just wanting to shift. I do know I have a 9" posi rear though! :thu
Anyway, I was just curious what you guys have. I had one friend recommend going to 3:73 and said he'd kick my butt if I went lower. Supposedly Gertrude is a bad b*tch the way she's built but I'd like to tone it down so Gertrude is a little more highway friendly. Oh and if I change the gear ratio, then I'll have to change my stall converter (which supposedly I have a large one) too?
Thinking of the future and possible Power Tour long haul. :roll
