However I can get it right every time. Jack the car up with the rear axel, both wheels off the ground if it is a sure grip, put the car in neutral, get under the car and have some one rotate the tire until the yoke is straight up and down. Mark the tire with a piece of chalk at the top or bottom, lay under the car and have a friend rotate the tire one rev at a time until the yoke has gone one full turn. If the wheel goes around four full times - and a bit - then you have a 4:10, it the wheel goes almost four times around - then you have a 3:91 - I hope your getting the picture by now. Earl I have a '64 Sport Fury, 383, automatic. I assume I have a standard axle with standard wheels and tires. How many different ratios are there for my car? I have lots of literature for my car, can I find it there? Thanks! ----------------------------------------------------------- Let University of Phoenix make 2004 your year.
