I've never restored a car, but what are the odds of putting in a modern six speed with over drive gears?

In a few articles I've read, they often suggest using a Ford 9 inch because it has a drop in third member for easy gear changes. That's all the info I can offer. Go with the 455 for sure. That'll be sweet.

I just put a 9" in my 67 with 4.11 gears. I took a chance with a company I found on Ebay called Quick Performance Racing but I couldn't be happier with my setup. My adjustable control arms came from UMI performance. This combo is a good bit less expensive than the Moser I put in my Camaro a couple years ago but is holding up to my abuse just fine.
