I'm getting ready to change out the rear end on my '69 and I'm torn between what gear ratio to go with. I'm looking at either a 3.50 or 3.70 third member from Speedway Motors, and I'm leaning towards the 3.70's. I swapped in an AOD out of a 92 gt a few years back just for this occasion, so I've got a .67 final drive. I'm running 24 wheels/tires, and it looks like I'd be turning about 2400 rpms at 70mph, which seems pretty reasonable. I'd just like a second opinion (maybe from someone who has done an AOD swap?) as to what gears you'd recommend, what you're running and how you like it? The car has a pretty mild 351w with just some basic bolt-ons and I don't ever plan on running more than 350-400hp when I do the motor. I mostly drive around town and to car shows, it's just a weekend toy not a daily driver. I doubt I'll ever take it out to the track or the strip, so I want something that will be fun to zip around town in without it thrashing the gears, but still able to drive down the highway at reasonable rpms to make it to a car show a few hours away. Thanks in advance.
