I'm trying to decide on a gear ratio for an engine / trans swap in my "other project" a 79 ranchero. I have a 4.11 posi that I once had in the 72 for a short bit. The math works out to a 2.75 final which seems decent to me. Any thoughts?

Sounds like a good plan to me, especially if you're in the hilly half of the state. Even 4.30s would net you a 2.88 final drive ratio with the AOD.

| An AOD overdrive ratio is .68,Times that by your gear ratio and that's your final gear ratio in od.You have been enlightened! |

This is my favorite speed/rpm/tire size/axle ratio calculator.
http://www.angelfire.com/fl/procrastination/rear.html I can figure the speed the car will travel given a set of parameters at whatever engine speed. And I can mess with different ratios and such to find out what would get me the right engine speed on the highways around here. ------------- 08 Uplander LS, 262K, broken again 08 Explorer EB, 195K, for the wife still looking for another something |

Perhaps http://ultimategto.com/art29.htm?engine=5000&trans=2.54%201.50%201.00%200.00%200.00%200.00%202.63&axle=3.55&tire=215%2070%2014&B1=Load%20Driveline%20Data%20into%20Top%20Speed%20Calculator - this one is a bit easier to use. You don't have to know the diameter of your wheel in inches. And http://www.allfordmustangs.com/Detailed/608.shtml - here is another, which goes the other way round. It tells you, what RPM you'll have at certain speeds. ------------- Tomi ______________________ http://www.ford-cruising.hu/gallery/thumbnails.php?album=31" rel="nofollow - 1975 Ford Gran Torino S&H 2005 Ford Mustang GT 2011 Ford S-Max |

You can't just hit Enter when you're done. You have to click the CALCULATE button or it just refreshes the screen. ------------- 08 Uplander LS, 262K, broken again 08 Explorer EB, 195K, for the wife still looking for another something |
