I know 80's didn't come with 33's and 4:11's
I was calculating for the way the car is going to be set up after the conversion. I could go to 35's if I really wanted to bring the rpm's down a little more but I prefer not to go that big. I read somewhere the decrease in economy for every 100 rpm's (above the most efficient) was pretty dramatic, like 10%, that could make the difference between 24 mpg at 2000 rpm, or 20 mpg at 2200 rpm. To me that would be worth messing with the gearing if that is in fact true, although I will still be very happy with an 80 that gets 20 mpg!
