tbird430 is on a distinguished road
Default 2.91 rear diff Gears

Just a side note for us 430cid powertrain Birders.

I know Bart Como, years back, beat me down this road on his rear diff overhaul. I have found that Richmond gear does off the original Ford 2.91 gear ratio for our rare birds!!

At a heafty $351.99 our original ratio can be replaced with a new ring & pinion gear set. I just recently ran into this problem myself and have decided to go back with a 3.00 ratio since it can be had for just $170.99.

Just wanted to make a note for anyone else in the future. I bought my overhaul items at

-Jon in TX.

The 1960 Ford Thunderbird. The WORLD'S most wanted car....
