I have a 63 with the 230 and 3-speed. My previous owner swapped in a 3.08's. I can get it up to 70-75 ..... in about 5 minutes, but I can get there. I lost most of my off the line power but it cruises great and I get roughly 17.5-18+ mpg.

My future plan is to install the 3 speed OD I bought so I can keep the three on the tree and go back to 3.73's. End result would be a 2.90 something final drive ration in 3rd OD. Still looks stock. No hacking the floor.

Look around for a 3 speed OD. They are out there. The price is slightly more than having the rear rebuilt end to end. I had a mustang rear done by the local specialist and it was $1000 with everything being rebuilt or replaced. Trans is about $1400.
