I'd get 27-28 mpg on 2 Lane roads going 62 in a 55mph. 72 on the freeway around 24, if I remember correctly. Switched to 3.73s 13 years ago. Been in the garage most of those years after trans went out.
I recently switched to 3.73 from my stock 3.08 5.0 lx and mpg went from 24.5 mpg at 74 mph to maybe 21 or 22 (any long drive involves hills in my area). I don't do long trips with it since doing mods but it was a 21% gear reduction using my math:grin2: so a fuel economy reduction is expected/guaranteed when you are in high gear and past about 1500 rpm.
As far as 0-60mph went for me. I switched to 3.73's in part to improve the time since it had to shift to second before it would hit 60mph. I remember not being able to hit 60 mph in first without hitting the 5000 rpm red line and I won't try it now with 3.73's. My tach does have a 500 rpm echo or something that can't really be trusted at high or WOT. Nobody has offered to time me so 0-60 is still a mystery.
Getting my 89 Cougar XR7 SC back on the road. No brakes and when I hit the brake pedal the VMM smoked. Is there any connection between the VMM and the brakes or was this a coincidence? Does anyone have a pinout for the VMM?

Hi everyone, I have a little problem. Not me, but the Cougar. Well, I do have problems... actually my problems have problems, but that is another story.
